Features

  • Self tapping thread profile enables immediate thread formation in sheet metal, eliminating pre-drilling for many gauge ranges.

  • Phillips drive enables reliable engagement with standard cross-slot drivers, reducing cam-out risk during installation.
  • Black oxide finish delivers corrosion resistance and wear protection suitable for interior or sheltered environments.
