• Secure fastening in plastic materials through TRS thread forming design that creates strong, permanent threads without chips
• Enhanced driving stability with tri-lobe shank cross-section that prevents rotation during installation
• Optimal material displacement with 1.34mm thread pitch specifically engineered for plastic applications
• Complete environmental compliance meeting RoHS 3 and REACH regulations for industrial safety standards
• Streamlined installation process with fully threaded blunt tip design for precise positioning in pre-drilled holes

Professional Applications & Engineering Value

These M3.63 TRS thread forming screws deliver exceptional performance in plastic fastening applications where traditional fasteners often fail. The 18-8 stainless steel construction provides superior corrosion resistance, making these metric tapping screws ideal for electronics enclosures, automotive components, and outdoor equipment where environmental exposure is a concern. The Torx Plus IP15 drive system ensures maximum torque transfer while minimizing tool wear and fastener damage. The tri-lobe shank design creates secure threads in plastic substrates without generating debris, eliminating the risk of contamination in sensitive assemblies. This combination of thread forming technology and premium material selection solves common challenges of strip-out, vibration loosening, and material degradation in plastic-to-plastic and plastic-to-metal joints.

Specification Summary & Compliance

This M3.63 x 5mm TRS plastic tapping screw features precision metric threading with a 1.34mm thread pitch and fully threaded blunt tip design. The fastener utilizes thread forming technology specifically engineered for plastic materials, requiring a 1/8" (0.125") drill bit for proper installation. Manufactured from 18-8 stainless steel with a Torx Plus IP15 (T15) drive and standard pan head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications.
