• Secure thread formation in plastics via tri-lobe shank design, creating strong, vibration-resistant assemblies without pre-tapped holes
• Optimized for plastic substrates with blunt tip and 0.79mm thread pitch, minimizing material stress and cracking during installation
• Enhanced installation efficiency with fully threaded design and standard pan head, allowing consistent seating and uniform clamping force
• Regulatory compliance assurance meeting RoHS 3 and REACH standards, supporting global supply chain requirements
• Precision compatibility with No. 51 drill bit (0.067"), ensuring proper hole sizing and reduced installation failures

Professional Applications & Engineering Value

Engineered specifically for plastic assembly applications, this M1.91 TRS tapping screw addresses critical challenges in modern manufacturing. The thread forming action combined with the tri-lobe shank cross-section displaces plastic material to create permanent, high-strength threads without generating chips that could contaminate sensitive components. This design eliminates the need for pre-tapped holes, reducing production steps and assembly costs. The Torx Plus IP6 drive system provides exceptional torque transfer, preventing stripping during high-volume installation while the zinc-plated steel finish ensures corrosion resistance in demanding environments. Ideal for electronics enclosures, automotive trim, and consumer products where reliable plastic-to-plastic or plastic-to-metal fastening is required.

Specification Summary & Compliance

This metric thread forming screw features M1.91 diameter with 12mm length and 0.79mm thread pitch, manufactured to precise dimensional standards for consistent performance. The TRS (Thread Rolling Screw) design with tri-lobe shank and blunt tip is optimized for plastic materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance. Installation requires No. 51 drill bit (0.067" diameter) for proper hole preparation.
