FHLS™ flush, low-displacement head studs are designed for installation into steel or aluminum sheets as thin as .040" / 1 mm, with a head profile that allows placement closer to the sheet edge than FH/FHS studs without bulging. The FHLS-440-10 variant is a #4-40 thread size, with a minimum sheet thickness of .040", a maximum installed height of .111", a minimum hole size of .138", and an attachment distance to edge of .085". The stud is compatible with sheets of hardness HRB 70 or less or HB 125 or less.
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.
