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.

Hex head self-drilling screws are characterized by their hexagonal head, which allows them to be driven using a wrench or a socket, providing an excellent grip and making them easy to install. What sets them apart is their unique ability to drill into materials without the need for pre-drilling, thanks to their sharp, self-tapping points. This feature not only saves time but also reduces the need for additional drilling equipment, making the installation process more efficient.
