Professional Applications & Engineering Value

These No. 12 sheet metal screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The zinc-plated steel construction provides essential corrosion protection in demanding industrial environments, while the thread forming design eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs. The combination of Phillips/Slotted drive offers flexibility for various tooling setups, and the pan head profile ensures stable driving without slippage. With a 1-1/2" length and fully threaded configuration, these tapping screws deliver consistent performance in HVAC systems, electrical enclosures, metal fabrication, and construction projects where secure fastening in thin-gauge materials is essential.

Specification Summary & Compliance

These No. 12 tapping screws feature a 0.216" thread diameter with 11 threads per inch and 1-1/2" length for precise sheet metal applications. The A/AB tapping screw type follows industry-standard thread forming specifications, requiring a 3/16" drill bit (0.1875" diameter) for proper installation in materials up to 0.025" maximum thickness. The right-hand thread direction and fully threaded design ensure consistent performance. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws meet the highest standards for environmental safety and industrial use.
