Professional Applications & Engineering Value

This M2.2 TRS thread forming screw is specifically engineered to address common challenges in plastic fastening, such as material cracking and weak thread retention. The 18-8 stainless steel material provides excellent strength and corrosion resistance, while the thread forming (TRS) design displaces plastic material to create strong, load-bearing threads without chips. This eliminates the need for additional inserts and reduces assembly time. The flat head with Phillips drive ensures a clean, flush finish in countersunk applications, making it ideal for electronics enclosures, automotive trim, and consumer products where aesthetics and reliability are critical. Its fully threaded configuration and right-hand thread direction offer uniform clamping force, enhancing vibration resistance in dynamic environments.

Specification Summary & Compliance

This screw features an M2.2 size with 8mm length, fully threaded design, and an approximate thread pitch of 0.98mm. It complies with standard metric threading and is manufactured for use with a No. 50 drill bit (0.07" diameter) and 90° countersink angle. The product adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial applications requiring strict environmental and safety standards.
