Flathead screws are bolts designed to fit inside a milled hole. A cutter is both the recessed hole and the tool to make the hole that allows compatible screws and bolts to screw out by flush with the surface. Flathead screws are mostly hidden when screwed, as their heads are shaped to fit special holes.
