  • 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

  • 1 The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
  • 2 Threads are gageable to within 2 pitches of the "S" Max. dimension. A class 3B/5H maximum material commercial nut shall pass up to the "S" Max. dimension.
  • 3 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
  • 4 HRB - Hardness Rockwell "B" Scale. HB - Hardness Brinell
  • 5 “X” suffix studs may have pitch diameters and major diameters below 2A “Basic”, per ANSI B1.1, Section 7, and B1.13M, Section 8 to allow for minimum of 0.0002” / 0.0051 mm of plating.
