A drywall screw is designed for attaching drywall to wood or metal studs. It is available with either coarse or fine threads. They are threaded along their entire length and are self-threading, this allows them to be installed without the need of apilot hole.
This bolt has a square shoulder under a rounded head (Mushroom Head) which resists turning when the nut is tightened or removed. The bolt is driven into a hole the same size as the shank and then hammered the rest of the way, where the square shoulder locks firmly into place.
