  • Excellent thread-forming capability creates permanent, vibration-resistant threads in steel and sheet metal without pre-drilling
  • Optimized drilling performance with specialized tip design that penetrates up to 0.09" thickness for efficient installation
  • Secure flush mounting achieved through the oval head design with 82° countersink angle for smooth, professional finishes
  • Enhanced driving efficiency with Phillips No. 2 drive that provides reliable torque transfer and reduces cam-out
  • Maximum holding power from fully threaded design that ensures complete engagement along the entire fastener length
  • Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 6 x 3/4" zinc-plated steel oval head tapping screws deliver exceptional value in demanding steel and sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for tapping operations while creating stronger, more durable threads that won't loosen under stress. The BSD tapping screw design combined with the drilling tip enables direct installation into materials up to 0.09" thick, significantly reducing assembly time and labor costs. The zinc-plated finish provides reliable corrosion protection, making these Phillips drive screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where long-term performance in challenging environments is essential.

Specification Summary & Compliance

These tapping screws feature precision 0.138" thread diameter with 20 threads per inch in right-hand orientation, manufactured to BSD standards for consistent performance. The thread forming tapping method ensures proper fit and maximum holding strength in base materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmentally responsible manufacturing and safe usage across various industrial sectors.
