Professional Applications & Engineering Value

These No. 12 zinc-plated 410 stainless steel tapping screws deliver exceptional engineering value in demanding industrial applications. The combination of thread forming technology and drilling tip design eliminates multiple installation steps, significantly reducing assembly time while creating stronger, more reliable connections in stainless steel and sheet metal up to 0.187" thickness. The integrated stainless steel/rubber sealing washer provides critical environmental protection against moisture ingress, making these fully threaded screws ideal for HVAC systems, electrical enclosures, and outdoor equipment where corrosion resistance and sealing integrity are paramount. The external hex drive ensures secure tool engagement even in high-torque applications, while the BSD tapping screw configuration guarantees consistent performance across production runs.

Specification Summary & Compliance

This No. 12 tapping screw features a 0.216" thread diameter with 14 threads per inch and 2-1/2" length, manufactured to precise dimensional standards for consistent performance. The thread forming design creates secure fastening without material removal. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The flat washer configuration with 0.563" OD provides optimal load distribution, while the drilling tip (No. 3 type, 9/32" length) enables efficient penetration through specified material thicknesses.
