Professional Applications & Engineering Value

These No. 12 x 3" oval head tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and long-term reliability are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these thread forming screws ideal for HVAC systems, electrical enclosures, and industrial machinery exposed to moisture or harsh conditions. The Phillips drive design ensures secure tool engagement during installation, while the fully threaded configuration maximizes pull-out strength in thin materials up to 0.025" thickness. The standard oval head with 82° countersink angle creates a flush, professional finish that eliminates snagging points and enhances aesthetic appeal in visible applications.

Specification Summary & Compliance

These tapping screws feature precise Class 2A thread tolerances with No. 12 thread diameter (0.216") and 11 threads per inch configuration. Manufactured to thread forming (Type A/AB) standards for sheet metal applications, they require a 3/16" (0.1875") drill bit for proper installation. The screws maintain full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest industrial safety and sustainability requirements for professional use.
