FHA-0420-6 is a flush-head self-clinching stud designed for installation in aluminum sheets with a Rockwell B hardness of 50 or less and a Brinell hardness of 82 or less. It features a 1/4-20 thread, a length of 0.249 inch, and is suitable for sheet thicknesses of at least 0.062 inch. The stud installs flush with the sheet surface and requires a minimum hole size of 0.250 inch with a minimum centerline-to-edge distance of 0.270 inch.
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.
