HFHB-0616-28X is a heavy-duty BUSBAR® self-clinching stud designed for superior electrical and mechanical attachment in copper sheets. It is a phosphor bronze stud with a 3/8-16 thread, 0.625 inch length, and a minimum sheet thickness of 0.090 inch. The stud projects above the sheet surface, distributing axial load to improve pull-through resistance. Its tensile strength is 60 ksi (415 MPa). The stud is recommended for use in copper sheets with a hardness not exceeding HRB 55 or HB 83. Electrical resistance between the stud and copper busbars is below 62 µΩ after repeated thermal and mechanical cycling for this size.
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
