Professional Applications & Engineering Value
This M2.63 Torx Plus TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out and material failure. The 18-8 Stainless Steel construction offers excellent durability and resistance to rust, making it suitable for electronics, automotive components, and outdoor equipment. The Tri-Lobe shank and thread forming design displace plastic material to create strong, permanent threads without chips, reducing assembly time and improving joint integrity. With the Torx Plus drive (IP8/T8), it delivers high torque transfer and minimizes cam-out, ensuring efficient installation in plastic applications where precision and reliability are critical.
Specification Summary & Compliance
This screw features an M2.63 size with an 8mm length, fully threaded with an approximate 1.06mm pitch, and a standard pan head design. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The thread forming (TRS) type and Tri-Lobe cross-section are optimized for use in plastics, with a recommended drill bit size of No. 43 (0.089") for proper installation.
