Drywall Screws (Coarse Thread)

Bugle Head: The smooth, curved shape under the head is designed to sink flush into materials without tearing the surface (such as the paper facing on drywall).
Coarse Threads: The wide spacing between threads provides an aggressive grip, making them ideal for securing drywall to wood studs.
Sharp Point: The very sharp tip allows the screw to easily pierce the material and start threading without the need for a pilot hole.
Black Finish: This is typically a black phosphate coating, which offers basic corrosion resistance and helps the screw drive more smoothly into the wood.
