HFHB-0518-24X is a heavy-duty BUSBAR™ self-clinching stud designed for superior electrical and mechanical attachment in copper sheets. It features a thread size of 5/16-18 and a length of 1.50 inches. The stud is made of phosphor bronze and is recommended for use in copper sheets with a maximum hardness of HRB 55 or HB 83. The phosphor bronze material provides enhanced electrical conductivity, with tested electrical resistance below 62 µΩ for this thread size after thermal and mechanical cycling. The stud installs in sheets as thin as 0.075 inch and requires a minimum hole diameter of 0.374 inch, with a minimum centerline-to-edge distance of 0.374 inch. The stud head projects above the sheet surface to distribute tightening force. Tensile strength is rated at 60 ksi (415 MPa).
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
