A low-friction lube finish helps our pocket hole screws sink in quickly for a tight hold. In addition, their self-tapping auger tips work like pilot bits, helping to eliminate splitting, and the flat bottomed heads seat securely in the pockets. Coarse thread pocket screws are an especially good choice for softwoods, since the deeper threads bite in deeper for a secure hold. The pan head design works with any stock, but excels in thinner stock since the compact head wont protrude from the shallower pocket.
