FHL-M4-8-ZI is a low-displacement head stud designed for permanent installation in aluminum or steel sheets with a thickness of 1.00 mm or greater. This stud type allows for installation closer to the edge of the sheet compared to standard flush-head studs, minimizing the risk of edge bulging. It is suitable for use in materials with a Rockwell hardness of 80 or less and a Brinell hardness of 150 or less. The stud provides high torque-out and pushout resistance, making it a reliable choice for applications requiring secure fastening in thin sheet materials.
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.
