Professional Applications & Engineering Value

These No. 12 zinc-plated steel thread forming screws deliver exceptional engineering value by addressing critical challenges in metal fabrication and assembly. The specialized thread forming design creates permanent, high-strength threads in steel and sheet metal without chip formation, eliminating contamination risks in sensitive environments. The integrated drilling tip with No. 3 geometry penetrates up to 0.187" thickness, streamlining installation while maintaining material integrity. The external hex drive provides superior torque transmission for secure fastening in high-vibration applications, while the flanged construction distributes clamping force evenly to prevent material distortion. These BSD tapping screws are engineered for production environments where reliability, speed, and consistent performance are paramount.

Specification Summary & Compliance

These thread forming screws feature precision No. 12 size with 0.216" thread diameter and 14 threads per inch configuration, manufactured to industry standards for dimensional accuracy. The right-hand threaded design with fully threaded shank ensures consistent engagement, while the 1-3/4" length provides optimal fastening depth. The zinc-plated steel construction meets corrosion resistance requirements, and the external hex drive complies with standard tooling specifications. These fasteners are suitable for professional steel and sheet metal applications where reliable performance and dimensional consistency are essential.
