HFHS-series self-clinching studs are heavy-duty fasteners designed for installation in steel or aluminum sheets as thin as 0.050" with a large head that projects above the sheet surface to distribute tightening force and improve pull-through resistance. They are recommended for use in materials with a Rockwell B hardness of 70 or less and a Brinell hardness of 125 or less, and provide high torque-out and pushout resistance. The stud features an annular groove and ribs that facilitate permanent embedding into the sheet during installation.
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
