Professional Applications & Engineering Value

This M2.2 x 18mm Phillips Pan Head TRS Tapping Screw is engineered to address common challenges in plastic assembly, such as strip-out and weak thread retention. The thread forming (TRS) design displaces material without cutting, creating strong, permanent threads in plastics that resist vibration and thermal cycling. Made from 18-8 Stainless Steel, it provides excellent resistance to oxidation and chemicals, extending service life in electronics, automotive components, and consumer goods. The fully threaded blunt tip and standardized pan head facilitate quick alignment and consistent torque application, reducing installation time and improving production efficiency in high-volume manufacturing.

Specification Summary & Compliance

This metric tapping screw features an M2.2 size with an approximate thread pitch of 0.98 mm and a length of 18 mm, adhering to standard dimensional tolerances for precision fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial applications. The screw is designed for use with a No. 50 drill bit (0.07" diameter) in plastic materials, supporting reliable performance in thread forming operations without additional tapping requirements.
