HFHS-style self-clinching studs are heavy-duty fasteners designed for installation in steel or aluminum sheets as thin as 0.050 in., with a head that projects above the sheet to distribute axial loads and improve pull-through resistance. They are rated for sheets with Brinell hardness up to 125 HB and Rockwell B hardness up to 85 HRB. The stud installs permanently using standard pressing equipment and provides high torque-out and pushout resistance. The part number HFHS-0518-8 is not explicitly listed, but the HFHS series is described with these specifications.
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
