Wafer Head and Truss Head Self Drilling Screws are specialized fasteners designed for secure installation in metal sheets, composite panels, and other thin materials. The wafer (low-profile) or truss (wide, slightly domed) head provides a large bearing surface, distributing load evenly and reducing the risk of material deformation. Made from high-quality carbon steel or stainless steel (A2-304 / A4-316), these screws offer excellent strength, corrosion resistance, and durability. The self-drilling tip allows fast installation without pre-drilling, and multiple drive options such as Phillips, Torx, or Hex provide flexibility for different tools and applications.
