Professional Applications & Engineering Value

These M3.5 tapping screws deliver exceptional engineering value in plastic assembly applications where material integrity and long-term reliability are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these TRS thread forming screws ideal for electronics enclosures, automotive plastic components, and outdoor equipment where environmental exposure is a concern. The Phillips pan head design offers a low-profile finish while the thread forming action creates strong, load-bearing threads in plastic substrates without requiring pre-tapped holes. This thread forming capability eliminates the risk of loose threads and ensures vibration-resistant fastening in plastic applications, reducing assembly time while improving joint integrity.

Specification Summary & Compliance

This metric tapping screw features M3.5 diameter with 14mm fully threaded length and 1.57mm thread pitch, manufactured to precise dimensional standards for consistent performance. The TRS (Thread Rolling Screw) type is specifically engineered for thread forming in plastic materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and safety in industrial applications, meeting the highest standards for hazardous substance restrictions in electronic and consumer products.
