FHA-440-10 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, suitable for sheet thicknesses of .040" / 1 mm and greater. The stud has a #4-40 thread and a 0.112" thread length. It installs permanently in aluminum, steel, or stainless steel sheets using standard press equipment, with high torque-out and pushout resistance. The head profile is flush, and the stud is available in steel, aluminum, or stainless steel materials. Dimensions are given in inches, with a minimum hole size of .085" and a minimum centerline-to-edge distance of .135". The part is part of the FHA series, which is optimized for softer aluminum sheets.
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.
