FHA-281-20 is a flush-head self-clinching pin designed for aluminum sheets with a Rockwell B hardness of 50 or less and a Brinell hardness of 82 or less, compatible with sheet thicknesses of at least .040 in. The pin has a nominal diameter of .281 in and a length of 2.5 in, with a minimum hole size of .312 in and a minimum centerline-to-edge distance of .38 in. It is available on special order and installs permanently in aluminum, steel, or stainless steel sheets using standard press equipment.
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.
