FH-256-4ZI is a self-clinching stud from the FH/FHS/FHA series, designed for permanent installation in aluminum, steel, or stainless steel sheets as thin as 0.020 inches (0.51 mm). These flush-head studs install with standard pressing equipment, embedding the head into the sheet to form a secure, flush assembly with high torque-out and pushout resistance. The FH type is suited for materials with Rockwell B hardness of 80 or less and Brinell hardness of 150 or less. The stud head projects no higher than the sheet surface, and all variants in this series are available in aluminum, 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.
