Professional Applications & Engineering Value

Engineered for demanding steel and sheet metal applications, these No. 12 hex head tapping screws deliver exceptional performance through their BSD thread forming technology and corrosion-resistant coated steel construction. The combination of thread forming tapping methodology creates permanent, vibration-resistant threads without chip generation, making them ideal for electrical enclosures, HVAC systems, and structural assemblies. The integrated steel/rubber sealing washer provides reliable environmental protection against moisture and contaminants, while the external hex drive ensures secure installation even in confined spaces. With 0.14" maximum drilling thickness capability and No. 2 drill tip design, these screws eliminate secondary operations, reducing assembly time and labor costs in industrial manufacturing and construction projects.

Specification Summary & Compliance

This No. 12 x 2" hex head tapping screw features precise 0.216" thread diameter with 14 threads per inch in right-hand orientation, manufactured to BSD thread forming standards. The fully threaded design with round shank cross-section ensures consistent performance, while the 0.563" OD flat washer provides optimal load distribution. Compliant with industry standards for tapping screws in steel and sheet metal applications, these fasteners meet quality specifications for dimensional accuracy and mechanical performance in industrial fastening systems.
