<p>A mounting/assembly element (2) intended for mounting with a draw tool, which is characterised in that a second end (10) of a rivet bush (7) is provided with a non cylindrical cross-section (36) which is suitable for cooperating engagement with an insertion tool (40), and that in the fast-mounted state of the mounting/assembly element (2), the part of a break zone (24) connected with a draw-head (22) for the deformation of a first end (8) of the rivet bush (7) is lying in the deformable first end (8) of the rivet bush (7). There is hereby established a counter-hold for torsion forces which arise with the dismounting and remounting of the nut (32), which means that a considerably greater tightening effect can be achieved, and also ensures that the mounting/ assembly element (2) can be reused (remounting of the nut (32)).</p> |
