Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional value in sheet metal assembly applications where vibration resistance and material integrity are critical. The Black Oxide 18-8 Stainless Steel construction provides superior corrosion protection while maintaining the strength characteristics needed for industrial environments. The fully threaded design and right-hand thread direction ensure maximum holding power across the entire fastener length, preventing loosening under dynamic loads. Engineered specifically for use with No. 21 drill bits, these screws create clean, precise threads in materials up to 0.025" thickness, eliminating the need for separate tapping operations and reducing assembly time significantly. The pan head profile with Phillips No. 2 drive offers reliable installation performance while maintaining a low-profile appearance ideal for confined spaces.

Specification Summary & Compliance

This No. 10-12 thread forming tapping screw features a 0.19" thread diameter with 12 threads per inch in a right-hand thread direction. The fastener meets industry standards for thread forming Type A/AB applications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 1" length and fully threaded configuration ensure consistent performance across the specified drilling thickness range, while the pointed tip facilitates easy starting and proper alignment during installation.
