Professional Applications & Engineering Value

These M3 x 18mm thread forming screws are specifically engineered to address common challenges in plastic assembly applications. The zinc-plated steel construction combined with the TRS thread forming technology creates durable, permanent threads in plastic materials without generating chips that could contaminate sensitive components. The Phillips No. 1 drive ensures reliable installation with standard tools, while the fully threaded design and 1.34mm pitch provide exceptional pull-out resistance. These metric tapping screws are ideal for electronics enclosures, automotive plastic components, and consumer products where vibration resistance and long-term reliability are critical. The blunt tip design prevents material splitting, making them perfect for thin-walled plastic assemblies.

Specification Summary & Compliance

These M3 x 18mm thread forming screws feature precision metric threading with standard pitch dimensions and are manufactured to exacting tolerances for consistent performance. The zinc-plated steel construction provides corrosion protection while maintaining mechanical strength. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance. The TRS thread forming design follows industry standards for plastic fastening applications, requiring a standard 2.25mm drill bit for proper hole preparation and optimal thread engagement.
