Professional Applications & Engineering Value

These M4 thread forming screws deliver exceptional value in plastic assembly applications where traditional fastening methods often fail. The TRS thread forming technology eliminates the need for pre-tapped threads by cold-forming precise mating threads directly into plastic substrates, creating stronger connections than conventional tapping screws. The zinc-plated steel construction provides essential corrosion resistance while maintaining the necessary strength for demanding industrial environments. The combination of Phillips No. 2 drive and pan head design ensures reliable installation with standard tools, reducing assembly time and improving production efficiency. These fully threaded screws distribute clamping force evenly, preventing stress concentration points that can lead to plastic cracking or failure under vibration and thermal cycling conditions common in automotive, electronics, and consumer product assemblies.

Specification Summary & Compliance

This metric TRS thread forming screw features M4 diameter with 18mm length and fully threaded right-hand configuration. Manufactured to precise dimensional standards with class 2A thread tolerances, the screw is designed for use with 3mm drill bits in plastic materials. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The thread forming tapping method creates strong, chip-free threads without requiring pre-tapped holes, making it ideal for high-volume plastic assembly operations where reliability and efficiency are critical.
