S-92400A480 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior vibration resistance and pull-out strength in plastic materials due to the advanced Tri-Lobe shank design that displaces material without creating chips
• Excellent corrosion resistance provided by 18-8 stainless steel construction, ensuring long-term reliability in various environmental conditions
• Quick and secure installation with external hex drive that prevents cam-out and allows for high torque application
• Reduced assembly costs through thread forming technology that eliminates the need for tapping operations and secondary cleaning
• Optimized for plastic applications with precise No. 32 drill bit compatibility (0.116" diameter) for perfect hole preparation
• Complete thread engagement with fully threaded design that maximizes holding power across the entire fastener length
• Environmentally compliant manufacturing meeting RoHS 3 and REACH standards for responsible sourcing and usage

Professional Applications & Engineering Value

This No. 6 TRS thread forming screw delivers exceptional engineering value for plastic assembly applications where vibration resistance and long-term reliability are critical. The Tri-Lobe shank cross-section creates permanent, high-strength threads in plastic materials through cold forming, eliminating the risk of stress cracking common with thread-cutting alternatives. Manufactured from 18-8 stainless steel, these screws maintain integrity in humid or corrosive environments, making them ideal for outdoor equipment, electronic enclosures, automotive components, and consumer products. The external hex drive ensures positive engagement with standard tools, reducing installation time while preventing damage to fastener heads. With precise compatibility for No. 32 drill bits, engineers can achieve optimal hole preparation for maximum thread engagement and holding power in various plastic substrates.

Specification Summary & Compliance

This thread forming screw features a No. 6 size with 1/2" length, 0.138" thread diameter, and 19 threads per inch. The TRS (Thread Rolling Screw) type with Tri-Lobe shank conforms to industry standards for plastic fastening applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance. The blunt tip design and fully threaded configuration provide consistent performance across the entire fastener length, while the external hex head (1/4" width) accommodates standard driving tools for reliable installation.
