Professional Applications & Engineering Value

This No. 8 x 7/8" Phillips Truss Head Tapping Screw is engineered to solve common challenges in sheet metal assembly, such as material stripping and weak thread retention. The 18-8 Stainless Steel provides excellent resistance to rust and corrosion, ideal for outdoor or humid environments. Its thread forming design displaces material to create strong, permanent threads without chips, reducing cleanup and improving joint integrity. The wide truss head offers a larger bearing surface, distributing clamp load effectively to prevent sheet metal deformation. With a right-hand thread and pointed tip, it ensures quick alignment and penetration, speeding up production lines in HVAC, automotive, and electronics enclosures where reliable, vibration-resistant fastening is critical.

Specification Summary & Compliance

This thread forming sheet metal screw adheres to standard inch measurements with a No. 8 screw size, 0.164" thread diameter, and 15 threads per inch.
