Wafer Truss Self Drilling Screw
Wafer/Truss Head Self Drilling Screws are fastening solutions designed for thin sheet metals, insulation panels, and light-gauge steel. They are manufactured to ASTM, DIN, and ISO standards in hardened carbon steel and stainless steel. The wide, low-profile head provides maximum bearing area to prevent pull-through of thin materials. With self-drilling tips, they allow quick installation without pre-drilling. They are widely used in HVAC ducting, insulation, sheet metal assemblies, and light construction applications.
