FHS-series self-clinching studs install permanently in aluminum, steel, or stainless steel sheets as thin as 0.020 in (0.51 mm), with a non-flush head that projects 0.025 in (0.64 mm) above the sheet surface. They are recommended for sheets with a Rockwell B hardness of 70 or less and Brinell hardness of 125 or less. The part features a clinching profile designed for secure installation via standard press tools, with torque-out and pushout resistance suitable for high-strength applications. The stud is threaded with a .190-24 UNF fastener size, and the head is identified by a dimple mark, consistent with TFH/TFHS designs. No exception is specified for FHS-024-20 beyond the series characteristics.
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.
