S-90390A137 6-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T10 Torx drive design that prevents cam-out and ensures secure fastening in demanding applications
• Enhanced corrosion resistance through zinc-plated steel construction, providing durable protection in various industrial environments
• Efficient material penetration with thread cutting design that creates precise mating threads in aluminum, brass, cast iron, and sheet metal
• Secure flush mounting with standard flat head profile and 82° countersink angle for smooth surface finishing
• Reliable coarse thread spacing (UNC) that provides excellent holding power and faster installation in softer materials
• Full threading capability ensuring maximum grip length and uniform stress distribution along the entire fastener
• Environmental compliance with RoHS 3 standards, making them suitable for regulated industrial applications

Professional Applications & Engineering Value

These 6-32 UNC tapping screws with thread cutting design solve critical fastening challenges in metalworking applications. The zinc-plated steel construction provides essential corrosion protection while maintaining structural integrity in harsh environments. The T10 Torx drive system delivers superior torque transmission compared to traditional drives, reducing tool slippage and preventing damage to fastener heads during high-torque applications. Engineered specifically for aluminum, brass, cast iron, and sheet metal, these screws create their own mating threads, eliminating the need for pre-tapped holes and streamlining assembly processes. The combination of coarse thread spacing and fully threaded design ensures rapid installation and maximum pull-out resistance, making them ideal for high-volume production environments where reliability and efficiency are paramount.

Specification Summary & Compliance

These industrial fasteners feature precise UNC thread standards with coarse thread spacing for optimal performance in various metals. The manufacturing adheres to strict dimensional tolerances with a standard 82° countersink angle for proper flush mounting. The screws are fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring they meet current environmental standards for hazardous substance restrictions. The right-hand thread direction and No. 6 screw size with 1/2" length provide consistent, reliable fastening performance across industrial applications.
