Pocket-hole joinery is popular because it is a fast, strong, easily adaptable, precise method of assembly. Joints are as strong as mortise-and-tenon joints and can be made in a fraction of the time. Award-winning Kreg Jigs® use a 3/5" counterbore bit with an 11/64" pilot to drill and 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 larger pan-head with a #2 Square recess and extended unthreaded shank enables the screw to draw the two members of the joint tight.
Pocket-hole plugs are cut at an angle so that they sit perfectly flush on the top of the screw head when fully inserted. A small amount of plug will remain above flush and will need to be trimmed off with a hand saw or sanded.
