Professional Applications & Engineering Value

These No. 12 x 1-1/2" 18-8 stainless steel Phillips flat head tapping screws are engineered specifically for demanding sheet metal applications where reliability and corrosion resistance are critical. The thread forming Type A design eliminates the need for pre-tapped holes while creating stronger thread engagement than cutting alternatives. The 82° countersink angle and flat head profile provide a clean, flush finish that prevents snagging and maintains aerodynamic surfaces. Manufactured from 18-8 stainless steel, these screws resist oxidation and chemical degradation, making them ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment exposed to moisture or temperature variations. The combination of thread forming technology and corrosion-resistant materials solves common challenges of strip-out, vibration loosening, and environmental degradation in thin-section metal assemblies.

Specification Summary & Compliance

These tapping screws feature a No. 12 screw size with 0.216" thread diameter and 11 threads per inch in right-hand direction. The fully threaded 1-1/2" length provides complete engagement capability, while the standard flat head profile with 82° countersink angle ensures proper seating. Manufacturing complies with Thread Forming Type A specifications for sheet metal applications, requiring a 3/16" (0.1875") drill bit for proper installation. The products are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
