Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Excellent holding power in plastics due to the Tri-Lobe shank design, which forms strong threads without creating chips.
- Easy installation and high torque capability provided by the external hex head, allowing for secure driving with standard tools.
- Reduced risk of material cracking as the thread forming (TRS) action displaces material rather than cutting it.
- Full thread engagement along the 1/2" length ensures maximum grip and uniform stress distribution.
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and suitability for regulated industries.
- Precise fit with No. 29 drill bit (0.136" diameter) for consistent, reliable performance in plastic assemblies.
Professional Applications & Engineering Value
This No. 8 TRS thread forming screw is specifically engineered for plastic applications, where traditional fasteners may fail. The Tri-Lobe shank cross-section and thread forming method displace plastic material to create strong, permanent threads without generating debris, eliminating the risk of contamination and weak points. Made from 18-8 stainless steel, it offers excellent corrosion resistance, making it suitable for outdoor, marine, or chemically exposed environments. The external hex drive and fully threaded design ensure easy installation and high clamp load, reducing assembly time and improving joint integrity in automotive, electronics, and consumer goods manufacturing.
Specification Summary & Compliance
This screw features a No. 8 size with a 0.164" thread diameter and 16 threads per inch, in a right-hand thread direction. It includes a 1/4" hex head and blunt tip for controlled penetration. Manufactured to precise standards for use with a No. 29 drill bit (0.136" diameter), it ensures accurate fit. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting strict environmental and safety regulations for industrial use.
