Professional Applications & Engineering Value

These M3.12 TRS tapping screws are specifically engineered for plastic applications, where traditional fasteners often cause splitting or stripping. The thread forming tri-lobe shank displaces material without cutting, creating strong, vibration-resistant threads that enhance joint integrity in components like electronic housings, automotive trim, and consumer goods. Made from zinc-plated steel, they resist corrosion in humid or demanding conditions, while the Torx Plus IP10 drive allows for higher torque application with minimal slippage, reducing assembly errors and improving production throughput. Ideal for high-volume manufacturing, these screws ensure reliable fastening in plastic assemblies, minimizing rework and downtime.

Specification Summary & Compliance

This M3.12 x 8mm screw features a right-hand thread with an approximate pitch of 1.27 mm, fully threaded for consistent engagement. It adheres to standard metric dimensions, including a head diameter of 5.6 mm and height of 2.4 mm, designed for use with a No. 37 drill bit. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for global industrial applications.
