Professional Applications & Engineering Value

These No. 12 sheet metal tapping screws are engineered specifically for thread forming applications in various metalworking industries. The 18-8 stainless steel composition provides exceptional resistance to corrosion and oxidation, making these Type A/AB screws ideal for outdoor equipment, HVAC systems, and electrical enclosures exposed to moisture and chemicals. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, vibration-resistant connections in sheet metal applications up to 0.025" thickness. The combination of right-hand threading and fully threaded design ensures consistent performance across manufacturing lines, while the square drive system prevents tool slippage and damage to fastener heads during high-torque installations.

Specification Summary & Compliance

These sheet metal tapping screws feature precise dimensional specifications including No. 12 screw size, 5/8" length, 0.216" thread diameter, and 11 threads per inch. The thread forming Type A/AB design complies with industry standards for self-tapping fasteners in metal applications. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for international industrial applications.
