HFHB-0420-16X is a heavy-duty BUSBAR® self-clinching stud designed for superior electrical and mechanical attachment in copper sheets. It has a 1/4-20 thread, installs in copper sheets up to 0.060 inch thick, and features a phosphor bronze material that provides low electrical resistance. The stud's head projects above the sheet surface and is recommended for use in copper with a Rockwell B hardness of 55 or less and a Brinell hardness of 83 or less. Tensile strength is 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
