HFHS™ heavy-duty self-clinching studs are designed for high-strength applications in steel or stainless steel sheets as thin as 0.050 inches, with a large head that projects above the sheet surface to improve pull-through resistance. They are rated for sheets with a maximum hardness of HRB 85 and HB 125. The stud installs permanently via press fitting into properly sized holes, offering high torque-out and pushout resistance. The head geometry supports high axial loading while maintaining a low displacements profile compared to standard flush-head studs. Available materials include steel and stainless steel, with performance dependent on base sheet properties.
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 .
HFHB (heavy-duty BUSBAR®) Studs are ideal for applications which demand superior electrical/mechanica
