Professional Applications & Engineering Value

This No. 10 flanged hex head tapping screw delivers exceptional performance in sheet metal fabrication and assembly applications. The thread forming design eliminates the risk of loose chips contaminating sensitive equipment while creating strong, permanent threads in pre-drilled holes. The combination of external hex drive and integrated flange provides superior installation efficiency, allowing for high-torque application without separate washers. With its fully threaded construction and precise 12 threads per inch configuration, this screw maintains consistent clamping force across the entire 1-1/2" length, preventing loosening from vibration in demanding industrial environments. The pointed tip ensures smooth material displacement during installation, reducing the risk of cross-threading while maximizing pull-out resistance in thin-gauge materials.

Specification Summary & Compliance

This thread forming tapping screw features a No. 10 size with 0.19" thread diameter and 12 threads per inch, designed for use with No. 21 drill bit (0.159" diameter). The flanged hex head measures 0.313" across flats with 0.151" height and 0.414" flange diameter. Manufactured to industry standards for sheet metal fastening applications, this right-hand threaded screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
