FHA-632-20 is a flush-head self-clinching stud designed for installation in aluminum sheets with a hardness of HRB 50 or less and HB 82 or less. It features a #6-32 thread and is intended for sheet thicknesses of .040" (1 mm) or greater. The stud installs permanently using a standard press, with a flush head that embeds into the sheet material to provide high torque-out and pushout resistance. The part is available in aluminum, steel, or stainless steel, with the FHA variant specifically recommended for softer aluminum sheets. Dimensions include a shank length of 0.206" and a minimum hole size of 0.160". The stud's clinching profile is designed to flow metal into an annular groove, securing the fastener without protrusion.
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.
FH (flush-head) studs are available in aluminum, steel, or stainless steel . They are also available unthreaded on special order.
