1" coarse pan head screw. 1" Coarse Thread self-tapping screws are specially designed for pocket hole joinery. They feature a self-tapping auger point that eliminates pre-drilling and a flat head that seats flushly in the bottom of the pocket hole. All of our screws utilize a No. 2 square drive recess. The deep recess of the square drive provides positive driver engagement to reduce cam-out. Like every Kreg product, our screws are manufactured from the highest quality materials.
