HFH-series self-clinching studs are heavy-duty fasteners designed for high-strength applications in aluminum, steel, or stainless steel sheets as thin as .050" / 1.27 mm, with a head that projects above the sheet surface to distribute tightening force and improve pull-through resistance. The stud head size and geometry enhance performance in materials with Brinell hardness up to 165 HB and Rockwell B hardness up to 85 HRB. These studs install permanently via press fitting into properly sized holes and offer high torque-out and pushout resistance. The series is available in steel and stainless steel variants, with performance ratings specified for these base materials.
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
