Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
  • Efficient installation through self-drilling tip design that eliminates pre-drilling requirements in steel and sheet metal up to 0.09" thickness
  • Enhanced driving control with Phillips No. 2 drive that provides secure tool engagement and reduces cam-out during installation
  • Optimized thread engagement through thread forming BSD design that creates strong, permanent fastenings without chip removal
  • Professional finish appearance with oval head profile that sits flush with surfaces while the 82° countersink angle ensures proper seating
  • Full-length fastening capability with completely threaded shank that distributes clamping force evenly across the entire 2" length
  • Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industrial applications

Professional Applications & Engineering Value

These No. 6 x 2" zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal fabrication applications. The combination of thread forming BSD technology and integrated drilling tip eliminates multiple installation steps, significantly reducing assembly time and labor costs. The fully threaded design ensures maximum pull-out resistance while the oval head with Phillips drive provides both aesthetic appeal and reliable torque transmission. Engineered specifically for industrial fastening challenges, these tapping screws maintain integrity in vibration-prone environments, making them ideal for HVAC systems, electrical enclosures, metal framing, and machinery assembly where durable fastening solutions are critical.

Specification Summary & Compliance

These tapping screws feature precision 0.138" thread diameter with 20 TPI thread pitch in right-hand orientation, manufactured to BSD tapping screw standards for consistent performance. The thread forming method creates strong internal threads in parent material without generating chips. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material transparency for industrial users worldwide.
