FHL-632-24ZI

Low-Displacement Head Studs – Types FHL, FHLS

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.

FHL (flush low-displacement head) Studs install closer to the edge of a sheet than PEM Types FH/FHS studs without causing that edge to bulge.- Installs closer to the edge of a sheet than PEM Type FH/FHS studs without causing that edge to bulge.

  • Flush-head for sheet thickness .040” and greater.
  • Type FHL is recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 80 or less and HB (Hardness Brinell) 150 or less.
  • Type FHLS is recommended for use in steel or aluminum sheets HRB (Rockwell “B” Scale) 70 or less and HB (Hardness Brinell) 125 or less.
