  • 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
