- Environmental compliance with RoHS 3 standards ensures safe use in regulated industrial applications
Professional Applications & Engineering Value
These Type B thread forming screws deliver exceptional value in sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread forming design eliminates the need for tapping operations and creates stronger threads by work-hardening the base material. The fully threaded No. 10-16 configuration ensures maximum engagement in thin materials, and the 82° countersink angle allows for perfect flush mounting that prevents snagging and maintains aerodynamic surfaces. The Phillips No. 2 drive offers familiar, reliable installation for production line efficiency.
Specification Summary & Compliance
This No. 10-16 x 5/8" tapping screw features inch system measurements with standard thread tolerances for consistent performance. The fastener meets Type B thread forming specifications and is designed for use with No. 21 drill bits (0.159" diameter). Manufactured with zinc-plated steel for corrosion resistance and featuring a standard flat head profile with 82° countersink angle. The product is fully compliant with RoHS 3 (2015/863/EU) regulations for environmental safety in industrial applications.
