Professional Applications & Engineering Value
These No. 12 tapping screws are engineered to address common challenges in metal fabrication, such as galvanic corrosion and installation inefficiency. The galvanic-barrier coated 18-8 stainless steel material prevents bimetallic corrosion when fastening dissimilar metals, extending service life in steel, stainless steel, and sheet metal assemblies. The integrated drill tip and thread forming design allow for rapid, one-step installation, reducing labor costs and minimizing hole preparation errors. With UNC coarse thread spacing and a flanged head, these screws deliver reliable clamping force and resistance to loosening under dynamic loads, making them ideal for HVAC, automotive, and construction applications where durability and speed are critical.
Specification Summary & Compliance
This flanged tapping screw features a No. 12 size with 1-1/2" length, 0.216" UNC thread diameter, and 14 threads per inch in coarse spacing. Manufactured to precise dimensional standards, it includes an external hex drive and fully threaded shank for consistent performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements for industrial use.
