FHS-M4-30 is a self-clinching threaded stud designed for permanent installation in aluminum, steel, or stainless steel sheets as thin as 0.51 mm. It features a flush head and is intended for use in sheets with a Rockwell B hardness of 70 or less and a Brinell hardness of 125 or less, offering high torque-out and pushout resistance. The stud installs with a standard press and embeds into the sheet material, forming a secure, flush assembly. The part belongs to the FHS series, which is available in aluminum, steel, or stainless steel and is suitable for metric thread sizes.
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.
