FHLS™ flush, low-displacement head studs install permanently in aluminum or steel sheets as thin as .040" / 1 mm and can be positioned closer to the sheet edge than FH/FHS studs without causing bulging. The FHLS type is recommended for sheets with a hardness of HRB 70 or less or HB 125 or less. This stud has a .138-32 thread size with a minimum installed sheet thickness of .040" and a minimum clearance hole size of .164". The stud's unthreaded length is .137" and its maximum head diameter is .190". It is designed for low-displacement installation while maintaining flush, secure attachment.
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.
