Professional Applications & Engineering Value

These TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications where traditional fastening methods often lead to material stress cracking or insufficient holding power. The Tri-Lobe shank design and thread forming technology displace plastic material rather than cutting it, creating zero clearance threads that significantly reduce the risk of stress concentration and subsequent failure. The Black-Oxide Steel construction provides essential corrosion protection while maintaining the mechanical strength required for demanding industrial environments. With precise 0.138" diameter and 19 TPI configuration, these screws deliver optimal performance when used with the recommended 1/8" drill bit, ensuring consistent results across high-volume production runs while minimizing installation errors and rework.

Specification Summary & Compliance

This No. 6 TRS tapping screw features precise dimensional specifications including 0.138" thread diameter, 1-1/8" length, and 19 threads per inch with fully threaded construction. The fastener meets industry standards for thread forming applications in plastic materials and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Phillips No. 2 drive and pan head design ensure compatibility with standard industrial driving tools while providing reliable fastening performance in plastic assembly operations.
