FHS series self-clinching studs are designed for permanent installation in aluminum, steel, or stainless steel sheets as thin as 0.020 in (0.51 mm), with high torque-out and pushout resistance. The FHS variant is recommended for use in sheets with a Rockwell B hardness of 70 or less and Brinell hardness of 125 or less. The stud has a flush head and installs with a standard press, embedding into the sheet material to form a secure, non-protruding joint. The part number FHS-256-12 corresponds to a #2-56 thread, 0.312 in length, with a minimum hole size of 0.085 in and a maximum centerline-to-edge distance of 0.187 in, and a head projection of 0.025 in above the sheet surface upon installation.
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.
