FHL and FHLS self-clinching studs are flush-head, low-displacement design fasteners for installation in aluminum, steel, or stainless steel sheets, offering reduced head diameter to allow installation closer to sheet edges compared to standard FH/FHS studs. Type FHL is suitable for sheets with hardness up to HRB 80 and HB 150, while FHLS is rated for sheets up to HRB 70 and HB 125. Both install in sheets as thin as 0.040 inch (1 mm).
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.
