• Environmental compliance meets RoHS 3 and REACH standards for safe use across regulated industries

Professional Applications & Engineering Value

These M3 TRS tapping screws are specifically engineered for plastic assembly applications where traditional fastening methods often fail. The thread forming technology eliminates the need for pre-tapped holes while creating strong, load-bearing threads that won't strip or loosen under vibration. Made from 18-8 stainless steel, these metric tapping screws resist corrosion in environments where moisture or chemicals are present. The combination of flat head design with 90° countersink ensures seamless integration into plastic housings, electronic enclosures, and automotive trim components. The fully threaded configuration maximizes surface contact area, distributing stress evenly to prevent plastic cracking or deformation - a common challenge in plastic fastening applications.

Specification Summary & Compliance

This M3 x 25mm TRS screw features metric dimensions with standard thread forming profile, 1.34mm thread pitch, and Phillips No. 2 drive compatibility. The manufacturing process adheres to precise dimensional tolerances suitable for plastic assembly requirements. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency for industrial applications. The product is designed to work with No. 41 drill bit (0.096") for optimal hole preparation in plastic materials.
