Today’s manufacturing environment continues to explore ways to use thinner sheet metal to reduce cost and weight. As material thicknesses decrease, fastening can become more problematic. SHEETtracs® is a self-tapping screw designed to be used in a pre-formed hole that produces assembly-safe metal joining.




SHEETtracs® fasteners use a compound-angled metric machine screw thread pitch to engage into sheet metal. The thinner asymmetric 45° thread flanks displace less material than common 60° threads, resulting in stronger female threads and increased thread engagement.


Diagram 1


The reverse flank angle in the thread-forming zone is designed to maximize the formed extrusion height. The thread-forming zone only affects the lead threads of the screw and ends before reaching the full body diameter of the thread.

The non-circular thread-forming zone enables simple concentric screw installation while minimizing thread-forming torque.

Reverse Flank 

A large clean extrusion is formed, allowing the circular screw body to resist against low strip torque, achieve higher clamp load, and provide a uniform tightening torque.

The solid full-body thread engagement elevates vibration resistance. Multiple reinsertions are achievable in applications requiring serviceability.
