Claims14
A fastening unit comprising:
- a blind rivet nut having a set head and a rivet shank;
- said set head being sized and configured to abut against a surface of a component having an opening that receives therein the rivet shank;
- a screw with a screw head and a threaded shank;
- and
- a washer being:
- held on the blind rivet nut by the screw;
- and
- axially retained between the screw head and the set head;
- said washer comprising a torque application surface and a projection projecting over the torque application surface at least in some sections,
- wherein the torque application surface and the projection are structured and arranged to interact with a tool to prevent said washer from rotating when the screw is rotated, and wherein said washer has a recess on its side facing towards the blind rivet nut, and a projection of the blind rivet nut is insertable into the recess.
