• Efficient and secure thread forming that creates strong, permanent threads without pre-tapping, minimizing installation time and effort.
• Easy installation with Phillips No. 2 drive, providing a common and user-friendly interface for consistent torque application.
• Optimized compatibility with No. 29 drill bits, ensuring precise hole sizing for reliable performance in plastic applications.
• Full threading along the 1" length for maximum grip and uniform stress distribution in assembled components.
• Compliance with RoHS 3 and REACH regulations, guaranteeing safe, environmentally responsible use in industrial settings.

Professional Applications & Engineering Value

This No. 8 x 1" TRS tapping screw is engineered to address common challenges in plastic fastening, such as material cracking and thread failure. The 18-8 stainless steel offers excellent durability and resistance to oxidation, while the thread forming technology and tri-lobe shank work together to displace plastic material gently, creating robust threads without inducing stress concentrations. Ideal for industrial applications in electronics, automotive, and consumer goods, this screw ensures reliable performance in assemblies requiring repeated disassembly and exposure to varying temperatures. Its Phillips drive and compatibility with standard No. 29 drill bits streamline production processes, reducing labor costs and enhancing overall efficiency in high-volume manufacturing environments.

Specification Summary & Compliance

This screw adheres to precise dimensional standards with a thread diameter of 0.164" and 16 threads per inch, ensuring consistent fit and performance. It is designed for use with a No. 29 drill bit (0.136" diameter) and features a fully threaded, right-hand thread forming design for secure installations. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious and regulated industrial applications.
