Our pocket hole screws feature self-tapping auger tips that work like pilot bits, helping to eliminate splitting. The flat bottomed heads seat securely in the pocket for a firm hold. Fine thread pocket screws are an especially good choice for hardwoods, since their less aggressive thread and shank help to prevent splitting. The pan head design works with any stock, but excels in thinner stock, because the compact head won't protrude from the shallower pocket.
