Professional Applications & Engineering Value
These No. 12 x 1-1/2" stainless steel sheet metal tapping screws deliver exceptional performance in demanding industrial applications where corrosion resistance and thread reliability are critical. The 18-8 stainless steel composition provides excellent durability against environmental factors, while the thread forming Type A/AB design creates strong, vibration-resistant threads in sheet metal up to 0.025" thickness. The combination of 11 TPI thread pitch and 0.216" thread diameter ensures optimal engagement in pre-drilled 3/16" holes, making these tapping screws ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where sheet metal fastening requires both strength and corrosion protection.
Specification Summary & Compliance
These thread forming screws feature precise No. 12 screw size with 1-1/2" length and fully threaded design. The Type A/AB tapping screw configuration ensures proper thread formation in sheet metal applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming these stainless steel fasteners meet current industry standards for restricted substances and chemical safety.
