A wafer head self-drilling screw, as the name suggests, is designed with a flat, thin, and round head that closely resembles a wafer. This design not only ensures a flush finish but also provides a broad surface area, distributing load evenly and reducing the chances of material splitting. The unique feature that sets it apart from conventional screws is its self-drilling capability. Equipped with a sharp point and specialized threads, these screws can penetrate through metal, wood, or plastic without the need for a pre-drilled hole, saving time and effort.
