Professional Applications & Engineering Value

This No. 10-12 thread forming screw is specifically engineered for demanding sheet metal applications, where vibration resistance and material integrity are critical. The 18-8 stainless steel composition offers excellent strength and corrosion resistance, preventing rust and degradation in industrial settings. Its thread forming (tapping) method displaces material to create robust internal threads, eliminating the need for separate nuts or tapped holes, which reduces assembly costs and potential failure points. The undercut oval head with an 82° countersink angle ensures a flush fit, minimizing protrusion and improving safety in equipment and enclosures. Compatible with a standard No. 21 drill bit, it streamlines procurement and installation processes, making it a reliable choice for HVAC systems, electronic chassis, and automotive panels where durability and regulatory compliance are paramount.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.19" and 12 threads per inch, ensuring precise fit in sheet metal applications. It features a fully threaded design with a right-hand thread direction and Class 2A thread fit for reliable engagement. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances and suitable for global industrial use.
