S-90380A147 Length 7/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
• Exceptional holding power in plastic materials through TRS thread-forming design that creates strong, permanent threads without pre-tapping
• Reduced installation torque and material stress thanks to the tri-lobe shank cross-section that displaces material efficiently
• Reliable drive engagement with Phillips No. 2 drive style preventing cam-out during installation
• Full-length threading ensures maximum thread engagement and pull-out resistance throughout the entire fastener length
• Optimized for plastic applications with blunt tip design that prevents material cracking during installation
• Compliance with international environmental standards including RoHS 3 and REACH for global manufacturing applications

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are engineered specifically for plastic fastening applications where traditional fasteners often fail. The thread-forming TRS design with tri-lobe shank creates secure, high-strength threads in plastic materials without generating chips or debris that can compromise assembly integrity. The 0.138" thread diameter and 19 threads per inch provide optimal thread engagement in various plastic densities, from soft thermoplastics to reinforced composites. The Phillips No. 2 drive ensures consistent installation torque transfer, while the rounded pan head offers a clean finished appearance with good bearing surface. These screws eliminate the need for pre-tapped holes, reducing assembly time and costs in plastic component manufacturing, electronic enclosures, automotive trim, and consumer products where reliable plastic-to-plastic or plastic-to-metal fastening is critical.

Specification Summary & Compliance

These No. 6 x 7/16" tapping screws feature precise 0.138" thread diameter with 19 threads per inch and fully threaded tri-lobe shank design for optimal performance in plastic applications. Manufactured to TRS (Thread Rolling Screw) standards with thread forming technology that creates strong mating threads in plastic materials. The screws maintain dimensional accuracy with standard inch system measurements and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions in industrial manufacturing.
