The FHLS-440-4 is a low-displacement head stud designed for permanent installation in aluminum or steel sheets with a maximum hardness of HRB 70 or Brinell hardness of 125. This stud type allows for installation closer to the edge of the sheet compared to standard flush-head studs, minimizing the risk of edge bulging. It is suitable for sheets as thin as 0.040 inches (1 mm) and provides high torque-out and pushout resistance. The FHLS series is particularly beneficial in applications where space is limited and a flush finish is required.
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.
