• Enhanced driving efficiency with fully threaded design and blunt tip, providing consistent engagement and simplified alignment in plastic assemblies
• Reliable fastening performance through thread forming (TRS) technology, eliminating chips and ensuring clean, secure installations in plastic materials
• Broad compatibility with standard No. 15 drill bits (0.18" diameter), streamlining installation processes and reducing preparation time
• Regulatory compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable manufacturing and workplace safety requirements

Professional Applications & Engineering Value

These No. 10 thread forming screws deliver exceptional engineering value in plastic fastening applications where material integrity and vibration resistance are critical. The zinc-plated steel construction provides durable corrosion protection for electronics enclosures, automotive components, and industrial equipment exposed to environmental factors. The Tri-Lobe shank design strategically displaces plastic material during installation, creating permanent, high-strength threads without generating particulate contamination - a crucial advantage in sensitive assemblies. The Torx Plus drive system (IP25/T25) ensures maximum torque transfer efficiency, reducing installation time and preventing fastener damage in high-volume production environments. These TRS tapping screws effectively solve common plastic fastening challenges including strip-out prevention, consistent clamp load maintenance, and assembly process optimization.

Specification Summary & Compliance

These precision-engineered fasteners feature a No. 10 screw size with 0.19" thread diameter and 14 TPI thread pitch, manufactured to exacting dimensional standards. The fully threaded design with right-hand threading and 1/2" length ensures consistent performance across applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms adherence to international environmental and safety standards, making them suitable for global industrial supply chains and regulated industries requiring documented material compliance.
