FHS-440-10 is a flush-head self-clinching stud designed for installation in steel or aluminum sheets as thin as 0.51 mm, with a recommended maximum hardness of HRB 70 or HB 125. The stud has a #4-40 thread and a 0.176 in (4.47 mm) long unthreaded shank. It features a dimpled head for secure clinching and installs permanently with standard press tools. The part is available in steel, aluminum, or stainless steel, and its design delivers high torque-out and pushout resistance.
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.
