The HFH-0420-12ZC is a heavy-duty self-clinching stud designed for high-strength applications. It can be installed in sheets as thin as 0.020 inches (0.51 mm) and is suitable for use in aluminum, steel, or stainless steel materials. The stud features a large head that projects above the sheet surface, which helps distribute axial tightening forces over a larger area, thereby enhancing pull-through resistance. This product is particularly effective in applications requiring high torque-out and pushout resistances. The HFH type is recommended for use in steel or aluminum sheets with a Rockwell hardness (HRB) of 85 or less and a Brinell hardness (HB) of 165 or less. Custom sizes are available upon request, making it adaptable for various engineering needs.
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
