Professional Applications & Engineering Value

These 18-8 stainless steel sheet metal tapping screws deliver exceptional engineering value in demanding industrial applications. The thread forming technology eliminates the need for separate tapping operations, creating strong, permanent threads directly in sheet metal substrates. The fully threaded design combined with the pointed tip ensures maximum engagement and pull-out resistance, solving common fastening challenges in thin-gauge materials. Ideal for HVAC systems, electronic enclosures, and metal fabrication projects, these Type A/AB screws provide reliable performance where vibration resistance and corrosion protection are critical. The right-hand thread direction and rounded pan head profile facilitate quick installation while maintaining a low-profile appearance in finished assemblies.

Specification Summary & Compliance

These precision tapping screws feature a No. 10 thread diameter (0.19") with 12 threads per inch and 1/2" length, manufactured to exacting dimensional standards for consistent performance. The thread forming Type A/AB design ensures proper thread engagement in sheet metal applications with maximum 0.025" drilling thickness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance for industrial use worldwide. Recommended drill bit size No. 21 (0.159" diameter) ensures optimal hole preparation for secure fastening performance.
