Professional Applications & Engineering Value

These No. 12 sheet metal tapping screws are engineered specifically for demanding industrial fastening applications where reliability and corrosion resistance are critical. The 18-8 stainless steel composition provides exceptional durability against moisture, chemicals, and temperature variations, making them ideal for outdoor equipment, HVAC systems, and electrical enclosures. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement than cutting screws, reducing installation time and preventing loose connections. The pan head design with one-way drive ensures secure installation and tamper-resistant properties, while the fully threaded 1-inch length maximizes surface contact for vibration-resistant performance in sheet metal assemblies up to 0.025" thickness.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 12 size with 0.216" thread diameter and 11 TPI right-hand threading, conforming to A/AB screw type standards. The fasteners maintain precise dimensional accuracy with Class 2A thread tolerances and are manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements. The pan head configuration with 0.425" diameter and 1/8" height ensures consistent performance across industrial sheet metal applications, supported by full regulatory documentation for quality assurance.
