Professional Applications & Engineering Value

These No. 8 x 1/4" zinc-plated steel TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications. The thread forming technology combined with the unique Tri-Lobe shank design creates secure, high-strength fastening points without generating chips or debris that can compromise electronic components. This makes them ideal for plastic enclosures, automotive trim, electrical housings, and consumer products where material integrity is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for durable assemblies. With 16 threads per inch and 0.164" thread diameter, these screws deliver optimal thread engagement in various plastic materials, preventing stripping and ensuring reliable performance in vibration-prone environments.

Specification Summary & Compliance

These TRS tapping screws feature precise thread forming technology with a Tri-Lobe shank cross-section and blunt tip design. The fasteners measure 1/4" in length with No. 8 screw size and 0.164" thread diameter, providing 16 threads per inch for optimal engagement in plastic materials. Installation requires a No. 23 drill bit (0.154" diameter) for proper hole preparation. The screws are manufactured to industry standards for thread forming applications and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and compliance requirements.
