Professional Applications & Engineering Value

These M3 x 20mm TRS tapping screws are specifically engineered for plastic assembly applications where traditional fastening methods fail. The thread-forming design eliminates the need for separate tapping operations, reducing production steps and minimizing the risk of plastic cracking. The zinc-plated steel construction maintains dimensional stability while providing essential corrosion protection in demanding environments. The Phillips drive system ensures reliable torque transmission during installation, while the flat head profile with 90° countersink creates seamless surfaces ideal for consumer products, electronic enclosures, and automotive plastic components. These metric tapping screws deliver consistent performance across high-volume manufacturing operations.

Specification Summary & Compliance

These fully threaded M3 screws feature precise metric dimensions with 20mm length and 1.34mm thread pitch, designed for use with 2.25mm drill bits. The TRS (Thread Rolling Screw) configuration follows standard thread-forming principles for plastic materials. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across international markets. The zinc-plated surface treatment provides consistent corrosion protection while maintaining electrical conductivity where required.
