HFHB-0518-12X is a heavy-duty BUSBAR® self-clinching stud designed for superior electrical and mechanical attachment in copper sheets. It features a phosphor bronze construction with a 5/16-18 thread, a nominal length of 0.312 inches, and a head that projects above the sheet material to improve pull-through resistance. It is recommended for use in copper sheets with a hardness of HRB 55 or less and HB 83 or less. Tensile strength is 60 ksi (415 MPa). The stud installs in copper sheets as thin as 0.075 inch. The part number includes a finish code 'X', indicating a specific plating or coating, consistent with the HFHB series design. This part belongs to the HFHB series, which shares the same installation method and mechanical performance characteristics.
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
