Professional Applications & Engineering Value
These No. 12 sheet metal tapping screws deliver exceptional engineering value for industrial fastening applications where corrosion resistance and thread integrity are critical. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure, making these thread forming screws ideal for HVAC systems, electrical enclosures, and metal fabrication projects. The Type A/AB thread forming design eliminates the need for pre-tapped holes while creating strong, vibration-resistant connections in sheet metal applications up to 0.025" thickness. The combination of square drive and pan head configuration ensures secure installation with standard tools, reducing assembly time and improving production efficiency in manufacturing environments.
Specification Summary & Compliance
These tapping screws feature precise No. 12 size with 2-1/2" length and 0.216" thread diameter with 11 threads per inch following standard thread forming specifications. The Type A/AB thread form ensures consistent performance in sheet metal applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance of material safety and regulatory compliance for industrial users.
