Professional Applications & Engineering Value

These Black Oxide 18-8 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 need for separate tapping operations, creating strong, vibration-resistant threads that withstand industrial stresses. The combination of No. 12 screw size with 11 threads per inch provides optimal thread engagement in thin materials, while the Phillips drive system ensures consistent torque application during high-volume assembly. These characteristics make them ideal for HVAC systems, electronic enclosures, automotive components, and industrial machinery where reliable metal fastening is critical to product performance and longevity.

Specification Summary & Compliance

This thread forming tapping screw features a No. 12 size with 0.216" thread diameter and 11 threads per inch, manufactured to standard inch measurements. The fully threaded design with pointed tip ensures easy starting and consistent thread formation. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance adherence. The screw is designed for use with 3/16" (0.1875") drill bits and accommodates maximum drilling thickness of 0.025" in sheet metal applications, providing reliable performance meeting industrial fastener standards.
