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
