Professional Applications & Engineering Value

These 1/4"-10 zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic fastening, such as material stress and thread stripping. The thread forming Tri-Lobe shank creates strong, permanent threads in plastic substrates without generating chips, reducing the risk of failure in plastic assemblies. Combined with the Torx Plus drive system, these screws deliver high torque transmission with minimal slippage, ideal for automated production lines and applications requiring repeated disassembly. The zinc-plated finish enhances corrosion resistance, making these industrial fasteners suitable for electronics enclosures, automotive components, and outdoor equipment where reliability is critical.

Specification Summary & Compliance

This product features a 1/4" thread diameter with approximately 10 threads per inch and a 3/4" length, fully threaded for consistent performance. It adheres to standard right-hand thread specifications and is designed for use with a T30 Torx Plus bit (IP30 drive). The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet stringent environmental and safety requirements for industrial use.
