Truss Head Self Drilling Screw

Truss head self-drilling screws feature a wide, low-profile domed head and a drill-point tip that eliminates the need for pre-drilling. The broad head provides excellent load distribution and minimizes pull-through, making them ideal for fastening thin metal sheets, HVAC ducts, and light steel structures. They ensure quick, clean, and secure installation in commercial and industrial applications.
