A bugle head that is designed to attach drywall to studs, and a phosphate finish.
A Drywall Screw is a self-tapping screw with more angular threads and a sharp pointed tip. As the name suggests, It is widely used on gypsum or drywall boards, and even on thin metal sheets and wood. It is easy to identify with its typical phosphate-black coating. A dimpler is always recommended for proper fixing of this screw.
