High-Tensile Strength Studs – Types HFG8™, HF109™

PEM® self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and into the annular groove – creating a flushhead assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.

HFH (heavy-duty) Studs replace weld studs with easier installation at lower costs. The large stud head which projects above the sheet material distributes the axial tightening force over a large area thereby improving pull through resistance.

HFG8 and HF109 (heavy-duty high tensile strength) Studs are manufactured for the most demanding applications from medium carbon alloy steel, then heat-treated to high strength and hardness qualities.- Types HFG8 and HF109 are for heavy-duty applications in sheets as thin as 1.000 mm.

  • Grade 8 and property class 10.9 studs meeting 150 ksi/1040 MPa minimum.
  • Recommended for use in steel or HSLA steel sheets HRB (Rockwell “B” Scale) 89 or less and HB (Hardness Brinell) 180 or less.
  • Large head diameter spreads compressive stress on panel.

To be sure that you are getting genuine PEM products, look for the PEM stamp. Studs within the size range of the SAE and ISO specs are also identified with the Grade 8 and 10.9 head markings respectively.
