Professional Applications & Engineering Value

These Black-Oxide Steel TRS plastic tapping screws are engineered specifically for plastic assembly applications where traditional fastening methods fall short. The innovative Tri-Lobe shank technology creates strong, permanent threads in plastic substrates through cold forming, eliminating chip formation and reducing stress concentrations. This thread-forming design provides exceptional resistance to vibration loosening, making these T8 Torx drive screws ideal for automotive components, electronics enclosures, and consumer products where reliability is critical. The Black-Oxide surface treatment offers consistent corrosion protection while maintaining dimensional stability, ensuring predictable performance in demanding industrial environments. With precise No. 2 thread diameter and 28 TPI configuration, these fasteners deliver optimal pull-out strength without compromising material integrity.

Specification Summary & Compliance

These plastic tapping screws feature a 1/2" length with fully threaded Tri-Lobe shank and 0.086" thread diameter in right-hand thread direction. The rounded pan head design with T8 Torx drive ensures secure installation with standard industrial tools. Manufactured to precise dimensional standards with Class 2A thread tolerances, these screws are designed for use with 5/64" (0.0781") drill bits in plastic materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures they meet the strictest international standards for industrial fasteners.
