Blind Rivet Nut for the Connection of Two Components

Abstract

A blind rivet nut for connecting two components via a screw connection is provided. The blind rivet nut includes a rivet shaft with an internal thread, on the axial first end of which shaft a deformation portion for producing the rivet connection is arranged, wherein a rivet head with a bearing surface for bearing an adjacent component surface is arranged on the axial second end of the rivet shaft. The bearing surface has a radial extent which is designed to be greater than or equal to 1.2 times the radial extent of the rivet shaft.
