• Easy installation using a No. 2 Phillips drive, providing common tool compatibility and reducing slip-out during torque application.
• Optimized for plastic materials with a blunt tip and fully threaded M3 x 8mm design, minimizing cracking and ensuring consistent holding power.
• Environmental and regulatory compliance with RoHS 3 and REACH, supporting sustainable manufacturing and global supply chain requirements.
• Precise fit with compatibility for No. 41 drill bits, ensuring accurate hole preparation and reducing installation errors.

Professional Applications & Engineering Value

These M3 TRS tapping screws are engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The thread forming action displaces plastic material to create robust, load-bearing threads without chips, enhancing joint integrity in applications like electronic enclosures, automotive trim, and consumer products. Made from 18-8 stainless steel, they resist rust and corrosion, extending service life in humid or industrial settings. The Phillips flat head design allows for seamless integration into plastic surfaces, while the 1.34mm thread pitch ensures reliable engagement. Ideal for high-volume production, these screws reduce the need for inserts and simplify inventory with their metric standardization.

Specification Summary & Compliance

This M3 x 8mm screw features a fully threaded design with a right-hand thread direction and standard flat head profile. It is manufactured to precise dimensional tolerances, including a head diameter of 5.5mm and compatibility with a No. 41 drill bit (0.096" diameter). The product adheres to industry standards for thread forming screws and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safety and environmental responsibility in global markets.
