Professional Applications & Engineering Value

This M2 TRS thread forming screw is engineered to address common challenges in plastic assembly, where traditional fasteners may strip threads or cause stress cracking. The 18-8 stainless steel material provides lasting corrosion resistance, while the Torx Plus T6 drive ensures maximum torque transfer without slippage—critical for high-volume production lines. Its thread forming design displaces material to create strong, permanent threads in plastics, eliminating the need for tapped holes and reducing assembly steps. With a fully threaded shank and right-hand direction, it offers uniform clamping force in electronics enclosures, automotive trim, and consumer goods, enhancing product longevity and reducing warranty claims.

Specification Summary & Compliance

This metric tapping screw meets precise dimensional requirements with M2 diameter, 4mm length, and 0.78mm thread pitch. It conforms to thread forming (TRS) standards for use in plastics, paired with a No. 52 drill bit (0.0635") for optimal hole preparation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety guidelines in industrial applications.
