FHLS-256-5 is a flush, low-displacement head stud designed for installation in steel or aluminum sheets as thin as 0.040″ (1 mm), with a thread size of #2-56 and a length code of 256. It installs closer to the edge of a sheet than standard FH/FHS studs without causing edge bulging, and is recommended for materials with a Rockwell B hardness of 70 or less and a Brinell hardness of 125 or less. The stud features a flush head and is suitable for applications requiring high torque-out and pushout resistance. Its physical dimensions include a minimum hole size of 0.085″ and a maximum head diameter of 0.112″. Installation requires a standard press and adheres to PEM's self-clinching design criteria.
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.
FHL (flush low-displacement head) Studs install closer to the edge of a sheet than PEM Types FH/FHS studs without causing that edge to bulge.
