Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional value in industrial fastening applications where time efficiency and reliability are paramount. The thread-forming BSD design creates permanent, high-strength threads in parent materials without chip removal, eliminating tapping operations and reducing installation time. The integrated drilling tip with 3/16" length and No. 2 configuration penetrates steel and sheet metal up to 0.098" thick, streamlining assembly processes in HVAC, metal fabrication, and construction applications. The zinc-plated finish provides essential corrosion protection for both indoor and moderate outdoor environments, while the Phillips drive system ensures compatibility with standard industrial tools. The oval head profile with 82° countersink offers a professional, flush finish that meets aesthetic requirements while maintaining structural integrity.

Specification Summary & Compliance

These thread-forming tapping screws feature precision BSD thread standards with 18 threads per inch and right-hand threading. The No. 8 screw size corresponds to 0.164" thread diameter with Class 2A tolerance for reliable fit. Manufacturing complies with industry standards for tapping screw applications, featuring fully threaded design and proper material specifications. The zinc-plated steel construction meets corrosion resistance requirements for general industrial use, while the dimensional accuracy ensures consistent performance across production runs. These fasteners are suitable for professional steel and sheet metal applications where drilling and tapping operations need consolidation.
