Professional Applications & Engineering Value

These 316 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the risk of metal chips contaminating sensitive equipment while creating stronger thread engagement than cutting alternatives. The flat head design with 82° countersink provides a smooth, flush finish that prevents snagging and maintains aerodynamic surfaces in HVAC systems, electronic enclosures, and automotive panels. The Phillips drive style offers reliable installation torque transfer, while the fully threaded No. 12 configuration ensures uniform stress distribution across the entire fastener length, preventing loosening from vibration and thermal cycling in demanding industrial environments.

Specification Summary & Compliance

These thread forming tapping screws feature precise Class 2A thread tolerances with 0.216" thread diameter and 11 threads per inch in right-hand direction. Manufactured to A/AB tapping screw standards with standard flat head profile and pointed tip for easy starting. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors without hazardous substance restrictions.
