HF109 heavy-duty, high tensile strength self-clinching studs are manufactured from medium carbon alloy steel, heat-treated to a minimum tensile strength of 1040 MPa, and meet property class 10.9 thread requirements. They are designed for installation in steel or HSLA steel sheets with a maximum hardness of HRB 89 or HB 180 and can be installed in sheets as thin as 1 mm. The stud features a large head that distributes compressive stress to improve pull-through resistance. The metric thread size M6 and length code 20 correspond to standard variants in the series, with a minimum sheet hole size of 6 mm and a maximum distance from the edge of 18.0 mm.
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
