Installs into thinner, harder, high strength steel materials (high strength steel sheets up to 700 MPa maximum ultimate tensile)
Allows overall weight reduction for all vehicles
Provides lower installed cost

Compare to other thin sheet fastening devices:

Addresses environmental concerns
Lighter weight
Close to edge of panel mounting
No embossing required
Hardened stud material provides stronger thread strength
Can be installed automatically using press or in-die technology
