Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
  • Efficient thread forming technology creates strong, permanent threads without chips or debris in steel and sheet metal
  • Integrated drilling tip eliminates pre-drilling requirements, saving significant installation time and labor costs
  • Full threading design ensures maximum grip length and uniform stress distribution across the entire fastener
  • Phillips drive compatibility provides widespread tool accessibility and controlled torque application
  • Oval head profile offers a finished appearance while maintaining excellent countersinking capability
  • Environmental compliance with RoHS 3 standards ensures safe use across regulated industries

Professional Applications & Engineering Value

These No. 6 x 1" zinc-plated steel tapping screws deliver exceptional value in steel and sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming BSD design creates precise mating threads through material displacement rather than cutting, resulting in zero clearance and superior resistance to loosening under dynamic loads. The integrated drilling tip with No. 2 geometry penetrates up to 0.09" thickness without pilot holes, streamlining assembly processes in manufacturing, HVAC ductwork, and metal framing. The zinc-plated finish provides essential corrosion protection in industrial environments, while the oval head with 82° countersink angle ensures flush mounting for both functional and aesthetic requirements.

Specification Summary & Compliance

These thread forming tapping screws feature precision No. 6 size with 0.138" thread diameter and 20 threads per inch in right-hand orientation. Manufactured to BSD tapping screw standards with fully threaded design and Class 2A thread tolerances for consistent performance. The product is RoHS 3 (2015/863/EU) Compliant, meeting international environmental regulations for industrial components.
