flat head press rivet bolt
Flush, low-displacement head studs install closer to the edge of a sheet than Types LFH/LFHS studs without causing that edge to bulge.
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.
