Professional Applications & Engineering Value

These M5 x 20mm TRS thread forming screws are specifically engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The 18-8 stainless steel offers excellent resistance to rust and chemicals, while the thread forming (TRS) design displaces plastic material to create robust, load-bearing threads without removing material. This eliminates debris and reduces the risk of cracking in brittle plastics. The Phillips flat head with 90° countersink allows for a smooth, flush surface finish, ideal for consumer electronics, automotive trim, and appliance housings where aesthetics and structural integrity are critical. By combining metric precision with optimized geometry, these screws deliver reliable holding power and streamline production in high-volume manufacturing environments.

Specification Summary & Compliance

This product features fully threaded M5 metric screws with an approximate pitch of 2.24mm, designed for use with No. 21 drill bits (0.159" diameter). The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free from hazardous substances. Manufactured to standard dimensional tolerances for thread forming screws, they are suitable for creating strong threads in plastic materials without additional tapping operations.
