When it comes to woodworking, using pocket hole joinery can be a great way to quickly and easily join boards together. However, it’s important to understand when it’s appropriate to use pocket holes and when it’s not. This all comes down to understanding wood expansion and contraction, which is affected by the relative humidity in the room or area where the wood is located.
Wood is made up of a bunch of straws that expand and contract based on the humidity and dryness of the wood. A good rule of thumb is that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity. It’s important to factor this into your designs to avoid problems later on.
While pocket hole screws are great for certain applications, there are also times when traditional joinery is necessary or when other fasteners should be used to avoid visible pocket holes or to account for wood expansion.
Key Takeaways
- Understanding wood expansion and contraction is crucial for knowing when to use pocket hole joinery.
- Pocket hole screws are great for certain applications, such as attaching face frames or making tabletops, but traditional joinery or other fasteners may be necessary in other situations.
- Plywood is very stable and can be used with pocket hole screws, but caution should be taken when using pocket hole screws in wide boards or when attaching table skirts.
Understanding Wood Expansion and Contraction
To determine when to use pocket hole joinery, it’s important to understand how wood expansion and contraction works. A piece of wood is made up of straws that bring water from the roots of the tree to the branches. The straws expand and contract based on the relative humidity and dryness of the wood.
For example, assume a 12-inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity. Hardwoods expand and contract more than softwoods, but this rule of thumb should work for most designs.
The expansion in a board goes across the grain, making it wider and narrower. The thickness may be affected slightly if it’s a thick piece, but typically it’s negligible. Plywood is built with the grain perpendicular on each ply, making it stable, and therefore, the expansion in plywood is negligible as well.
Pocket screws can be used on boards that will not change in length, but not on boards that will expand and contract over time. Pocket screws can be used on plywood, which is very stable. They are commonly used in cabinet carcasses and for attaching face frames onto cabinet boxes.
Pocket screws are great for attaching two boards at a 90-degree angle, making a tabletop, or a dresser top. The screws act as clamps while the glue dries. However, when drilling a pocket hole, it makes an oval-shaped hole that is typically not desirable on a piece of furniture.
Traditional joinery is preferred for some applications, such as attaching a skirt to a tabletop or attaching something horizontally into a wide board. In these cases, pocket hole screws should not be used.
Wood expansion can be controlled by locking the position in place with screws or using brackets with slots. It’s important to design furniture so that pocket holes are on the back side or not seen at all.
The Role of Humidity
Wood is made up of a collection of straws that expand and contract based on the humidity and dryness of the environment. The expansion and contraction of the wood must be taken into account when using pocket hole joinery. A humidity sensor can be used to monitor the range of humidity in a workshop.
A rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity. Plywood is very stable because the grain is perpendicular on each ply, so the expansion in plywood is negligible.
Pocket screws can be used on plywood, but should not be used on boards where the screws are across the grain. Pocket screws can be used for attaching face frames onto cabinet boxes, making tabletops and dresser tops, and in other applications where the wood will not expand in length.
However, pocket screws should not be used when the oval shaped hole made by drilling a pocket hole is visible, or when traditional joinery is preferred. When attaching a skirt to a tabletop, pocket screws should not be used because the tabletop will expand to the right and left.
Techniques such as using tabletop fasteners or blocks can be used to attach tabletops while still allowing for expansion and contraction. Wood expansion can be controlled by using screws directly into the bottom of the wood along the back edge, or by using brackets with slots in them.
When attaching something into a wide board, pocket hole screws should not be used because they do not account for the expansion and contraction across the width of the board.
Rule of Thumb for Wood Expansion
To properly use pocket hole joinery, it is important to understand wood expansion and contraction. Wood is made up of a collection of straws that expand and contract based on the humidity and dryness of the environment. A good way to visualize this is to imagine blowing air through a piece of wood with large pores such as oak and seeing bubbles form.
To account for wood expansion and contraction, assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity. Hardwoods will expand and contract slightly more than softwoods. The expansion will occur across the grain, making the width of the board the most important factor to consider.
Plywood is built with the grain running perpendicular on each ply, making it stable and reducing the potential for expansion and contraction. Pocket screws can be used in plywood without issue, making them a common choice for cabinet carcasses and attaching face frames.
Pocket hole joinery is suitable for attaching boards that will not change in length, such as when attaching two boards at a 90 degree angle. They can also be used when making a tabletop or dresser top, as long as the bottom is hidden and enough glue is used to keep the boards together.
However, pocket screws should not be used when the oval shaped holes left behind are visible on both sides of the board. Traditional joinery is a better option in these cases. Additionally, when attaching a skirt to a table top, pocket screws should not be used as the table top will expand in both directions. Other fasteners such as figure eight fasteners or z brackets should be used instead.
It is also important to consider wood expansion when attaching something to a wide board or when only wanting the wood to expand in one direction. In these cases, pocket hole screws may not be suitable.
Concerns About Wood Width
When using pocket hole joinery, it is important to consider the expansion and contraction of wood. Wood is made up of straws that expand and contract based on the humidity and dryness of the environment. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity. Hardwoods typically expand and contract more than softwoods, but as long as this rule of thumb is factored into designs, problems can be avoided later on.
It is important to note that expansion will occur across the grain of the wood, making the width of the board the primary concern. Plywood, on the other hand, is built in a way that counteracts expansion and contraction, making it stable and suitable for pocket hole joinery.
Pocket screws can be used in a variety of applications, such as attaching face frames or making tabletops. However, it is not recommended to use pocket screws when drilling into the end grain of a board or when attaching a skirt to a tabletop. Traditional joinery may be more appropriate in these situations.
If wood expansion needs to be controlled in a specific direction, screws can be placed directly into the wood along the back edge to lock its position in place. Alternatively, brackets with slots can be used on the front edge to allow for expansion and contraction in that direction.
Overall, it is important to consider the width of the wood and the potential for expansion and contraction when deciding whether or not to use pocket hole joinery.

The video explains the benefits of Ralph Chapman’s guide about setting up an affordable workshop and avoiding the most common mistakes offers to anyone interested in woodworking.
Plywood Stability
When it comes to wood expansion and contraction, it is important to understand that the straws in a piece of wood will expand and contract based on the relative humidity in the room or area where it is located. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity. Hardwoods will typically expand and contract slightly more than softwoods.
In terms of plywood stability, the way it is built with the grain running perpendicular on each ply makes it very stable. This means that the expansion in plywood is pretty much negligible because the cross grains counteract any expansion and contraction that happens. As a result, pocket screws can be used pretty much anywhere in plywood. They are commonly used in cabinet carcasses and for attaching face frames onto cabinet boxes.
Pocket screws are also great for attaching boards at a 90 degree angle, such as for making a tabletop or dresser top. If the bottom of the tabletop is going to be hidden, pocket screws can act as clamps while the glue dries.
However, pocket screws should not be used when attaching something into a wide board or when attaching a skirt to a tabletop. They should also not be used when the oval shaped hole created by the pocket hole would be visible on both sides of the furniture piece. In these cases, traditional joinery or other fasteners such as figure eight fasteners or z brackets should be used.
It is important to consider wood expansion and contraction when designing furniture pieces and to choose the right type of joint for each application.
Proper Use of Pocket Hole Screws
When using pocket hole joinery, it is important to understand wood expansion and contraction. Wood is made up of straws that expand and contract based on the relative humidity in the room or area. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity. Hardwoods typically expand and contract more than softwoods, but as long as this is factored into designs, problems will be avoided.
When using pocket screws, it is important to consider whether the board will change in length. If screws are placed across the grain, the board may expand and contract over time, causing buckling, splitting, or cracking. Plywood is very stable due to the perpendicular grain on each ply, making pocket screws suitable for use in cabinet carcasses and attaching face frames.
Pocket screws are also useful for attaching boards at a 90 degree angle, making tabletops or dresser tops, or acting as clamps while glue dries. However, if the pocket holes will be visible on both sides of a piece of furniture, traditional joinery may be a better option. Additionally, pocket screws should not be used to attach a skirt to a tabletop as the tabletop may split or warp as it expands and contracts. Tabletop fasteners, such as figure eight fasteners or z brackets, should be used instead.
Wood expansion can be controlled by attaching screws directly into the bottom of a board along the back edge or using brackets with slots on the front edge. Pocket screws should also not be used to attach something horizontally into a wide board.
Pocket Screws in Plywood
When it comes to wood expansion and contraction, it’s important to understand that a piece of wood is made up of straws that can expand and contract based on the humidity and dryness of the environment. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity. Hardwoods typically expand and contract more than softwoods, but as long as you factor this into your designs, you should be fine.
It’s important to note that wood expands across the grain, so the width of the board is what you need to be concerned about. Plywood, on the other hand, is built with the grain running perpendicular on each ply, making it very stable. This means that pocket screws can be used pretty much anywhere in plywood, making it a popular choice for cabinet carcasses and attaching face frames onto cabinet boxes.
Pocket screws are also great for attaching two boards at a 90 degree angle, such as for making a tabletop or dresser top. The screws can act as clamps while the glue dries, ensuring a flat surface. However, it’s important to remember that when you drill a pocket hole, it creates an oval-shaped hole in the board, which may not be desirable for pieces of furniture where the holes will be visible. In these cases, traditional joinery may be a better choice.
There are also instances where pocket screws should not be used, such as when attaching a skirt to a tabletop. This is because the tabletop will expand to the right and left, and using pocket screws may cause the board to split or warp over time. Instead, there are other options such as tabletop fasteners or blocks that can be used to attach the tabletop while still allowing for expansion and contraction.
Overall, pocket screws are a great option for certain applications, but it’s important to understand when to use them and when not to. By factoring in wood expansion and contraction, you can ensure that your projects will last for years to come.

Pocket Screws in Board Joinery
When it comes to using pocket hole joinery in woodworking, it’s important to understand how wood expansion and contraction works. Wood is made up of tiny straws that expand and contract based on the humidity and temperature of the environment. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity.
Pocket screws are a great option for joining boards together in certain applications, such as attaching face frames onto cabinet boxes or making tabletops. They can act as clamps while the glue dries and are stable in plywood due to the way it’s constructed.
However, there are also times when pocket screws should not be used. For example, when attaching a skirt to a tabletop, as the tabletop will expand and contract in width and could cause the board to split or warp. Traditional joinery is also preferred in certain situations, such as when making a big farm table with mortise and tenon joinery.
It’s important to consider the direction of wood expansion and contraction when using pocket screws. To control the direction of expansion, screws can be placed directly into the wood in a specific direction. When attaching something into a wide board, pocket screws should be avoided as they do not account for the expansion and contraction across the width of the board.
Overall, pocket hole joinery can be a useful technique in woodworking, but it’s important to understand its limitations and when it’s appropriate to use.
Pocket Screws in Tabletop Construction
When it comes to woodworking, it’s important to understand wood expansion and contraction. A piece of wood is made up of straws that expand and contract based on the relative humidity in the room or area. An easy rule of thumb is to assume that a 12-inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity.
Hardwoods tend to expand and contract more than softwoods, but as long as you factor in the expansion and contraction in your designs, you should be fine. The expansion in a board will go across the grain, making the width the primary concern. Plywood is very stable and can be used with pocket screws almost anywhere, which is why they’re commonly used in cabinet carcasses.
Pocket screws are great for attaching face frames onto your cabinet box, making a tabletop or dresser top, or attaching two boards at a 90-degree angle. If the bottom of your tabletop is going to be hidden, pocket screws can actually act as clamps while the glue dries.
However, there are times when pocket screws should not be used. When drilling a pocket hole, it makes an oval-shaped hole in your board, which is typically not something you want to see on a piece of furniture. If you have something that will be seen on both sides, it’s not a good application for a pocket screw. Traditional joinery is also a better option for certain projects, such as a big farm table made with mortise and tenon joinery.
One place you should never use pocket screws is attaching a skirt to a tabletop. The table top will expand to the right and left, and using pocket screws can cause the board to split or warp over time. Instead, use tabletop fasteners such as figure eight fasteners, z brackets, or sliding blocks in mortise and tenon.
Lastly, be mindful of wood expansion when attaching something into a wide board. Pocket hole screws do not account for the expansion and contraction across the width of the board, so it’s best to use other fasteners or methods in these situations.
When Not to Use Pocket Screws
Pocket hole joinery is a great way to join two pieces of wood together, but it’s not always the best option. When deciding whether or not to use pocket screws, it’s important to consider the wood’s expansion and contraction. Wood expands and contracts based on the relative humidity in the room or area where it is and the dryness of the wood.
A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity. Hardwoods typically expand and contract more than softwoods, but if this rule of thumb is followed, there should be no issues.
When it comes to plywood, the way it’s built makes it very stable, and the expansion in plywood is pretty much negligible because the cross grains counteract any expansion and contraction that happens. This makes plywood a great option for using pocket screws pretty much anywhere, especially in cabinet carcasses and for attaching face frames onto cabinet boxes.
However, there are times when pocket screws should not be used. For example, when drilling a pocket hole, it makes an oval-shaped hole in the board, which is typically not something you want to see on a piece of furniture. If the pocket holes will be visible on both sides, it’s probably not a good application for a pocket screw.
Traditional joinery is also a great option when pocket holes are not suitable. For example, a big farm table that was all traditional mortise and tenon joinery with no fasteners would be a great option.
Another time when pocket screws should not be used is when attaching a skirt to a tabletop. The tabletop will expand to the right and left, and using pocket screws may cause the board to split or warp as it expands and contracts over time. There are other options such as tabletop fasteners, figure eight fasteners, z brackets, or sliding blocks in a mortise and tenon that can be used instead.
It’s also important to consider wood expansion when attaching something into a wide board. If the board is going to expand and contract across the width, it’s best not to use pocket screws.
Overall, pocket screws are a great option for joining two pieces of wood together, but it’s important to consider the wood’s expansion and contraction and whether or not pocket screws are the best option for the specific project.
Avoiding Visible Pocket Holes
Pocket hole joinery can be a great way to join pieces of wood together, but it’s important to understand when and where to use it. When designing with wood, it’s crucial to consider the expansion and contraction of the material due to changes in humidity and temperature. A piece of wood is made up of straws that expand and contract based on the relative humidity in the room or area where it is located.
To avoid visible pocket holes, it’s crucial to know when not to use them. For example, if a board is going to change in length, it’s not recommended to use pocket holes across the grain as it may cause buckling, splitting, cracking, or separation over time. However, using pocket screws on plywood is generally safe since the cross grains counteract any expansion and contraction that may occur.
A great application for pocket hole joints is attaching face frames onto cabinet boxes or making a tabletop. When attaching a skirt to a tabletop, it’s not recommended to use pocket hole screws since the table top will expand to the right and left, and the board may split or warp over time. Instead, consider using tabletop fasteners such as figure eight fasteners, z brackets, or sliding blocks in a mortise and tenon.
It’s also important to consider wood expansion when attaching something into a wide board horizontally. In this case, it’s not recommended to use pocket hole screws since it does not account for the expansion and contraction across the width of the board.
In summary, pocket hole joinery is a useful technique, but it’s essential to understand its limitations and when not to use it. By factoring in the expansion and contraction of wood, one can avoid visible pocket holes and ensure a long-lasting joint.
Traditional Joinery Vs Pocket Holes
When deciding whether to use traditional joinery or pocket holes, it’s important to consider wood expansion and contraction. Wood expands and contracts based on the relative humidity and season, and the width of the board is the most affected by this. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity. Plywood, on the other hand, is very stable due to its perpendicular grain construction.
Pocket holes are great for attaching face frames onto your cabinet box, making tabletops, and building shop cabinets. They act as clamps while the glue dries and are very stable in plywood. However, they should not be used for attaching a skirt to a tabletop or anything that will be seen on both sides. Traditional joinery is preferred in these cases.
To control wood expansion, screws can be placed directly into the bottom of the wood along the back edge to lock it in place, while brackets with slots can be used on the front edge to allow for expansion in that direction. It’s important to avoid using pocket holes when attaching something horizontally into a wide board or when joining across the grain, as this can cause buckling, splitting, or cracking over time.
Avoiding Pocket Screws for Table Skirts
When it comes to wood expansion and contraction, it is important to understand that the straws in a piece of wood will expand and contract based on the relative humidity in the room or area. A quick rule of thumb is to assume that a 12-inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity. This expansion will go across the grain, making the width of the board the main concern.
While pocket screws are commonly used in cabinet carcasses, they should not be used for attaching a skirt to a tabletop. This is because the tabletop will expand to the right and left, and pocket screws may cause the board to split or warp as it expands and contracts over time. Instead, there are various options for fasteners or blocks that can be used to attach the tabletop while still allowing for expansion and contraction. A Google search for tabletop fasteners can provide options such as figure eight fasteners, z brackets, or sliding blocks in a mortise and tenon.
It is also important to note that pocket screws should not be used when attaching something into a wide board or when traditional joinery is required. When drilling a pocket hole, it creates an oval-shaped hole in the board, which may not be suitable for pieces of furniture that will be seen on both sides. Additionally, traditional joinery may be more appropriate for certain projects, such as a big farm table with all mortise and tenon joinery.
To control wood expansion, screws can be directly inserted into the bottom of a board along the back edge to lock its position in place. However, on the front edge with a live edge, brackets with slots can be used to allow for movement and expansion in that direction.
In summary, pocket screws are a useful tool for certain applications, but it is important to understand when they should and should not be used. When attaching a skirt to a tabletop, it is best to avoid pocket screws and opt for other fasteners that allow for expansion and contraction.
Tabletop Fasteners
When it comes to woodworking, it’s important to understand the concept of wood expansion and contraction. Wood is made up of small tubes that expand and contract based on the humidity and temperature of the environment. A good rule of thumb is to assume that a 12 inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity.
Pocket hole joinery is a popular method for joining boards together, but it’s important to know when and where to use it. For example, pocket screws can be used on plywood because the cross grains make it stable and prevent expansion and contraction. Pocket screws can also be used on tabletops and other large surfaces as long as they are hidden and not seen on both sides.
However, pocket screws should not be used on boards that will expand and contract across the grain, such as attaching a skirt to a tabletop. In these cases, tabletop fasteners such as figure eight fasteners or z brackets should be used to allow for expansion and contraction.
It’s important to understand when to use pocket hole joinery and when not to in order to avoid splitting, cracking, or separation of the wood over time. By following these guidelines, woodworkers can ensure their projects are sturdy and long-lasting.
Controlling Wood Expansion
Wood expansion and contraction is a natural process that occurs due to changes in the relative humidity and dryness of the wood. To prevent problems caused by wood movement, it is important to understand how it works and how to control it. A good rule of thumb is to assume that a 12-inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and the humidity.
When it comes to using pocket screws, it’s important to consider the direction of wood movement. Pocket screws can be used on boards that won’t change in length, but should not be used across the grain as this can cause buckling, splitting, or cracking over time. Plywood, on the other hand, is very stable due to its cross-grain construction and can be used with pocket screws in most applications.
Pocket screws are great for attaching face frames, making tabletops, and building cabinets. They can also act as clamps during the glue-drying phase. However, they should not be used in applications where the oval-shaped hole created by the pocket screw will be visible, or where traditional joinery is preferred.
It’s important to note that when attaching a skirt to a tabletop, pocket screws should not be used as the tabletop will expand and contract over time. Instead, tabletop fasteners such as figure eight fasteners or sliding blocks in mortise and tenon joints should be used.
To control wood expansion, screws can be directly inserted into the bottom of the wood along the back edge to lock that position in place. Brackets with slots can also be used on the front edge to allow for expansion in one direction only.
Overall, understanding wood movement and how to control it is essential when using pocket screws in woodworking projects.
Avoiding Pocket Screws in Wide Boards
When it comes to using pocket hole joinery, it’s important to understand the expansion and contraction of wood due to changes in humidity and temperature. A piece of wood is essentially a collection of straws that expand and contract based on the relative humidity in the room or area. A 12-inch wide board can expand or contract about an eighth of an inch in either direction depending on the season and humidity, which is important to consider when designing with pocket screws.
While plywood is generally stable due to the way the grains are aligned, using pocket screws on wide boards or across the grain can cause buckling, splitting, or cracking over time. However, pocket screws can be used for attaching face frames, making tabletops, and building cabinets where the plywood is stable.
It’s important to avoid using pocket screws on visible surfaces or when traditional joinery is preferred. Attaching a skirt to a tabletop with pocket screws can also cause warping and splitting, so alternative fasteners like figure-eight fasteners or sliding blocks in mortise and tenon joints should be used.
Controlling wood expansion can be achieved by using screws directly into the bottom of a board along the back edge, or using brackets with slots for expansion at the front edge. Overall, understanding the limitations and best practices of pocket hole joinery can help avoid issues with wood expansion and maintain the integrity of furniture and woodworking projects.
Using Dado for Shelf Construction
When it comes to constructing shelves, one option to consider is using dado joints. Dado joints are created by cutting a groove into one board and then fitting another board into that groove. This creates a strong and stable connection between the two boards.
One advantage of using dado joints for shelf construction is that they can help prevent sagging. Because the shelves fit snugly into the grooves, they are less likely to sag under the weight of the items placed on them.
Dado joints can also be used to create adjustable shelves. By cutting multiple grooves into the sides of a cabinet or bookcase, shelves can be easily moved up or down as needed.
Another benefit of using dado joints is that they can be hidden from view. By cutting the grooves on the inside of the cabinet or bookcase, the joints are not visible from the outside, creating a cleaner and more streamlined appearance.
Overall, dado joints can be a great option for shelf construction. They are strong, stable, and can help prevent sagging. Plus, they can be hidden from view for a more polished look.
Pocket Screws in Narrow Boards
When it comes to pocket hole joinery, it is important to understand wood expansion and contraction. Wood is made up of straws that expand and contract based on the relative humidity in the room or area. A 12-inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity. Hardwoods typically expand and contract more than softwoods.
Expansion in a board will go across the grain, making the width the main concern. Plywood is very stable due to the cross-grain construction, making it suitable for pocket screws anywhere. Pocket screws are also great for attaching face frames and making tabletops.
However, pocket screws should not be used across the grain of a narrow board as it may cause buckling, splitting, cracking, or separation. When drilling a pocket hole, it makes an oval-shaped hole in the board, which is typically not desirable on a visible piece of furniture. Traditional joinery is a better option for visible pieces.
It is also not recommended to use pocket screws when attaching a skirt to a tabletop as the tabletop will expand to the right and left. There are many options for fasteners or blocks to attach tabletops while allowing for expansion and contraction, such as figure eight fasteners, z brackets, or sliding blocks in mortise and tenon joints.
In instances where wood expansion needs to be controlled, screws can be placed directly into the bottom of the wood along the back edge to lock its position in place. Slots in brackets can also be used to allow for expansion in specific directions. It is also not recommended to use pocket screws when attaching something horizontally into a wide board.
Efficiency of Pocket Hole Joinery
Wood expansion and contraction are important factors to consider when deciding whether to use pocket hole joinery. A piece of wood consists of straws that expand and contract based on the relative humidity in the room and the dryness of the wood. For instance, a 12-inch wide board will expand or contract about an eighth of an inch in either direction depending on the season and humidity.
Hardwoods typically expand and contract more than softwoods, but the rule of thumb still applies. The expansion in a board goes across the grain, making the width the primary concern. Plywood is stable because the cross grains counteract any expansion and contraction that happens. Therefore, pocket screws are commonly used in plywood, such as in cabinet carcasses and attaching face frames.
Pocket hole joints are also useful for making tabletops. By drilling pocket holes across the boards, the screws act as clamps while the glue dries. Once the glue dries, the screws don’t do much, but they help in the clamping phase to keep everything flat.
However, pocket screws are not suitable for all applications. For example, when drilling a pocket hole, it makes an oval-shaped hole in the board that may not be desirable for visible furniture. Also, pocket screws should not be used to attach a skirt to a tabletop because the tabletop will expand to the right and left, causing the board to split or warp over time.
Overall, pocket hole joinery is an efficient way to join pieces of wood together, but it is essential to consider the expansion and contraction of the wood to avoid any issues later on.
