Phillips wafer head self-drilling screws with blue-white zinc electroplating are mainly used for fastening thin metal studs, aluminum sheets, and gypsum boards. The wide wafer head provides a larger contact surface, allowing the driving force to focus on the drill point. This enables the screw to quickly penetrate 0.8mm–1.2mm metal sheets without the need for pre-drilling, significantly improving installation efficiency.
The wafer head also helps to evenly distribute the load, reducing the risk of material cracking during fastening. Surface finishes are available in electroplated blue-white zinc, grey phosphate, and black phosphate, providing corrosion protection for different environments.
We offer various sizes including 13mm wafer head tek screws, 1/2 wafer head self drilling screws, and steel self drilling screw zinc plated finish wafer head options. These self drilling corrosion resistant ribbed wafer head screws are ideal for interior construction, drywall installation, and light steel frame systems.
