FHLS-440-16 is a flush, low-displacement head self-clinching stud designed for installation in steel or aluminum sheets as thin as 0.040" (1 mm). It has a #4-40 thread and is recommended for sheets with a Rockwell B hardness of 70 or less and a Brinell hardness of 125 or less. The stud installs closer to the edge of a sheet than standard FH/FHS studs without causing bulging, and its head remains flush with the sheet surface after installation.
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.
