Professional Applications & Engineering Value

These No. 8 x 1/2" TRS tapping screws are specifically engineered for plastic applications, addressing common issues like material cracking and fastener back-out. The thread forming design creates strong, permanent threads in plastic without pre-tapping, reducing assembly time and tooling costs. Made from zinc-plated steel, they offer enhanced corrosion resistance for indoor and mild outdoor use. The Torx Plus IP20 drive ensures maximum torque transfer, minimizing slippage and damage to screw heads during high-speed automation. Ideal for industrial fastening in electronics, automotive trim, and consumer goods, these screws provide reliable holding power in brittle or soft plastics, improving product longevity and reducing maintenance needs.

Specification Summary & Compliance

This product features a No. 8 screw size with a 1/2" length and 16 threads per inch, ensuring precise fit in plastic components. The tri-lobe shank cross-section and blunt tip support effective thread forming, while the Torx Plus T20 drive provides consistent engagement. Manufactured to common industrial standards for tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of hazardous substances and supporting global supply chain requirements.
