  • Installs into thin, harder, high strength steel materials (high strength steel sheets at 975MPA maximum ultimate tensile)
  • Allows overall weight reduction for all vehicles
  • Provides lower installed cost
  • Unplated threads may be oversized sized as permitted by thread standards to accept minimum plating thickness of .00020”/.0051 mm
Compare to other thin sheet fastening devices:
  • Addresses environmental concerns
  • Smaller outer diameter
  • Lighter weight
  • Flush on reverse side of panel
  • Close to edge of panel mounting
  • No embossing required
  • Hardened nut material provides stronger thread strength
  • Can be installed automatically using press or in-die technology

  • 1 Other shank and screw lengths available.
  • 2 For maximum performance, we recommend that you use the maximum shank length for your sheet thickness.
  • 3 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
  • 4 HRC - Hardness Rockwell "C" Scale. HB - Hardness Brinell.
  • 5 Unplated threads are sized to accept a basic go gauge after .00025 in plating.
  • 6 “BL” suffix will be added to part number to designate DuraBlack™ finish.
