HFLH-0518-16X

Type HFLH™ Hard Panel Studs

HFLH-0518-16X

Type HFLH™ Hard Panel Studs

  • 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
