Wafer Head & Truss Head Self Drilling Screws
Wafer Head and Truss Head Self Drilling Screws are high-performance fasteners specifically designed for fastening sheet metal, composite panels, light-gauge steel, and other thin materials. Featuring a large bearing surface, the wafer head (low-profile) and truss head (wide domed) designs help distribute clamping force evenly, reducing the risk of material deformation while providing a clean and professional finished appearance.
Equipped with a precision self-drilling point, these screws can drill, tap, and fasten in a single operation, eliminating the need for pre-drilling and significantly improving installation efficiency. Their self-drilling capability reduces labor time while ensuring secure thread engagement and reliable holding strength.
Manufactured from premium carbon steel or corrosion-resistant stainless steel (A2-304 and A4-316), Wafer Head and Truss Head Self Drilling Screws offer excellent mechanical strength, long service life, and superior resistance to rust and environmental exposure. They are widely used in construction, metal fabrication, HVAC systems, steel framing, and panel installation projects.
