Key Features & Benefits at a Glance

  • Superior corrosion resistance with black-oxide steel finish for extended service life in demanding industrial environments
  • Efficient thread-forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
  • Optimized for sheet metal applications with pointed tip and No. 10-12 thread size for quick starts and secure fastening
  • Enhanced driving control with Phillips No. 2 drive and pan head design prevents cam-out and provides flush installation
  • Maximum material penetration with fully threaded shank and 12 threads per inch for superior holding power
  • Precision compatibility with No. 21 drill bits (0.159") for streamlined installation in materials up to 0.025" thickness
  • Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These black-oxide steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread-forming A/AB type design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The fully threaded configuration with pointed tip ensures rapid penetration and maximum thread engagement in materials up to 0.025" thickness. The Phillips pan head provides excellent torque transmission while maintaining a low-profile finish, ideal for applications where clearance is limited. These industrial screws are engineered to prevent stripping and maintain integrity through repeated thermal cycles and vibration exposure common in sheet metal applications.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerances and consistent 12 threads per inch. The thread-forming tapping method follows industry-standard A/AB specifications for reliable performance in sheet metal substrates. These fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. Designed for optimal performance with No. 21 drill bits (0.159" diameter) in specified material thicknesses.
