Professional Applications & Engineering Value
This No. 8 TRS tapping screw is specifically engineered for plastic fastening applications, where traditional screws may strip or crack the material. The thread-forming design with a tri-lobe shank displaces plastic to create strong, permanent threads, eliminating the need for inserts and reducing assembly steps. Made from 18-8 stainless steel, it resists rust and corrosion, making it ideal for outdoor enclosures, electronic housings, and automotive plastic components. The Phillips drive ensures quick, secure installation with standard tools, while the blunt tip and fully threaded profile prevent damage to delicate plastic structures, ensuring reliable performance in high-vibration environments.
Specification Summary & Compliance
This screw features a No. 8 size with 0.164" thread diameter and 16 threads per inch, adhering to standard inch measurements for precise fit. The pan head style with 0.322" head diameter provides a low-profile, secure fastening. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
