FHS-440-5 is a flush-head self-clinching stud designed for installation in steel or aluminum sheets as thin as 0.020 in (0.51 mm), with a thread size of #4-40. It features a clinching profile that ensures high torque-out and pushout resistance, and is recommended for use in materials with a Rockwell 'B' hardness of 70 or less and a Brinell hardness of 125 or less. The stud's head design allows permanent installation through pressing, with a minimum hole size of 0.176 in and a maximum hole distance from the edge of 0.219 in. The part belongs to the FHS series of flush-head studs, available in steel or stainless steel.
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.
