Pocket hole joinery is popular because it is a fast, strong, easily adaptable, precise method of assembly. Joints are as strong as mortise & tenon joints and can be made in a fraction of the time. Award-Winning Kreg Jigs use a 3/8” counterbore bit with an 11/64” pilot to drill a 15° angle into the first piece.With the joint tightly clamped, a special self-drilling “pocket hole” screw is placed in the pocket and driven tight to complete the joint.
Pocket Hole screws feature an auger point to prevent raising a chip between the two parts during assembly, ensuring a tight joint. A large pan head with a #2 Square Recess and extended unthreaded shank enable this screw to draw the two members of the joint tight.
