FHA-440-16 is a flush-head self-clinching stud designed for installation in aluminum sheets with a hardness of HRB 50 or less and HB 82 or less. It has a nominal thread size of #4-40, a thread length of 0.111 inches, and is suitable for sheet thicknesses of .040 inches and greater. The stud installs permanently by embedding into the sheet material using a standard press, providing high torque-out and pushout resistance with a flush head profile. All dimensions conform to the FHA stud series specifications.
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.
