FH-M4-25ZI is a flush-head self-clinching stud in the FH series, designed for permanent installation in aluminum, steel, or stainless steel sheets as thin as 0.51 mm. It installs with a standard press, embedding its head to form a flush assembly with high torque-out and pushout resistance. The FH series is suitable for sheets with hardness up to HRB 80 and HB 150. The stud is available in aluminum, steel, or stainless steel and can be ordered unthreaded on special request.
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.
