Professional Applications & Engineering Value
These M3.12 TRS plastic tapping screws are engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The tri-lobe cross-section and thread forming design create strong, lasting threads in plastics without pre-tapping, reducing assembly steps and labor costs. Made from 18-8 stainless steel, they offer excellent resistance to corrosion and wear, making them suitable for electronics, automotive interiors, and consumer goods exposed to moisture or chemicals. The Torx Plus IP10 drive ensures high torque application with minimal slippage, enhancing productivity in automated or manual fastening processes. This combination of precision threading and durable materials ensures reliable performance in demanding industrial applications.
Specification Summary & Compliance
This screw features a metric M3.12 size with a 10mm length and 1.27mm thread pitch, designed for use with a No. 37 drill bit (0.104" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The thread forming (TRS) type and fully threaded design adhere to standard industrial practices for plastic fastening, providing consistent performance and ease of integration.
