Pocket Screw Joinery used in combination with other joinery types: Although this would not be strong enough to be used in projects where the joint would be subjected to higher forces, such as in benches, there is still a valuable place for this kind of joinery in your projects. When compared to using dowels or moritse and tenon joinery, pocket hole joinery is considered to be the least strong of the 3. Some tests have shown that a pocket hole joint can withstand forces of up to 100 pounds. The speed at which the pocket hole joint can be made and it's relative strength make it an attractive option for wood joints. The clamping force of the screw is what distinguishes this joint from other traditional woodworking joints that typically count on glue and intricate mechanisms to mate the wood pieces together. Once a screw is inserted into the drilled hole and into it's mating wood piece, the screw essentially acts as a clamp keeping the wood pieces together. The angle at which the hole is drilled is typically 15 degrees. The hole is drilled with a stepped counter bore drill bit that creates a narrow hole for the screw shank as well as a flat bottomed shoulder for the screw head to seat against. Making your own pocket screw hole plugsĪlthough sometimes performed free-hand by seasoned woodworkers, a jig is most often used to control the angle and depth at which the pocket hole is made.Deciding where to drill the pocket holes.
