Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal assembly applications where corrosion resistance and structural integrity are paramount. The Type B thread forming design eliminates the need for tapped holes, creating strong internal threads through material displacement rather than cutting. This results in zero chip generation, preventing contamination in sensitive industrial environments while providing superior resistance to vibration loosening. The Phillips flat head with 82° countersink angle ensures flush mounting in panels and enclosures, while the fully threaded configuration maximizes engagement in thin-gauge materials. Engineered for durability and consistent performance, these tapping screws significantly reduce installation time and improve assembly reliability in HVAC, electrical enclosures, and metal fabrication projects.

Specification Summary & Compliance

This No. 4-24 x 3/8" tapping screw features standard inch measurements with Class 2A thread tolerances and Type B thread forming specifications. The screw maintains precise dimensional accuracy with 0.212" head diameter, 0.067" head height, and fully threaded shank. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications. Installation requires a No. 44 drill bit (0.086" diameter) for optimal thread formation in sheet metal substrates.
