FHLS™ flush, low-displacement head studs are designed for installation in steel or aluminum sheets as thin as 0.040" (1 mm) with a maximum hardness of HRB 70 or HB 125. The stud installs closer to the edge of a sheet than standard FH/FHS studs without causing edge bulging. The FHLS-440-12 variant has a #4-40 thread, a length code of 12 (0.750"), and is intended for use with sheets meeting the specified hardness limits.
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.
