Blind rivet nut for a screw connection and manufacturing method of a blind rivet nut

摘要

A blind rivet nut 1 according to the invention for a screw connection between a carrier component and a fastening component comprises a sleeve-shaped shaft 10 with an internal thread 16. The sleeve-shaped shaft 10 can be inserted into a fastening hole of the carrier component and has a fastening flange 20 at a first end and a foldable one to form a bulge Folding zone 12, which can be supported on opposite sides of the carrier component. On a radially outer side, the fastening flange 20 comprises knurling 22 and axial projections 24 on the side facing the shaft and / or axial projections 26 on the side of the fastening flange 20 facing away from the shaft, which are arranged directly adjacent to the radial outside. In this way, when using the blind rivet nut 1, a coating of the carrier component and / or the fastening component can be pierced by means of the axial projections 24, 26 and an electrical contact can be produced by means of the blind rivet nut 1.
