Clinch bolt with shaft with profiled tie part and lock nut shaft part

摘要

The clinch bolt (1) has a cylindrically round functional shaft part (7) which supports elements. It protrudes outwards over the length of the rivet hole and that part of the lock nut shaft part gripped by the lock nut ring. The axial length (l) of the functional shaft part is at least half the diameter (d) of the clinch bolt near the rivet hole. The tie part (9) is joined to the functional shaft part by a nominal fracture point (8) for detaching the two parts.
