High-Strength Studs for Thin Sheets – Type HFE
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.
HFE (heavy-duty) Studs are designed with an enlarged head diameter which projects above the sheet material and provides maximum pull through in sheets as thin as .040”.- Enlarged head diameter provides high-strength in sheets as thin as .040”.
- Recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 85 or less and HB (Hardness Brinell) 165 or less.
