• Precision metric sizing with M3.12 diameter and 12mm length ensuring consistent fit and performance in plastic assemblies

Professional Applications & Engineering Value

These M3.12 TRS tapping screws are specifically engineered for plastic fastening applications where material integrity is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for durable assemblies. The innovative tri-lobe shank design enables true thread forming action that displaces plastic material rather than cutting it, creating stronger threads with reduced stress concentration. Combined with the Torx Plus IP10 drive system, these screws deliver maximum torque transfer without stripping, making them ideal for high-volume production environments. The 1.27mm thread pitch and fully threaded configuration ensure consistent engagement depth and pull-out resistance in various plastic materials, from thermoplastics to composite assemblies.

Specification Summary & Compliance

These metric thread forming screws feature M3.12 diameter with 12mm length and 1.27mm thread pitch, designed for use with No. 37 drill bit (0.104" diameter). The TRS tapping screw type with tri-lobe shank cross-section ensures proper thread formation in plastic materials. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, providing assurance for use in regulated applications. The Torx Plus IP10 (T10) drive system maintains precise dimensional tolerances for consistent performance in industrial fastening operations.
