The present invention concerns a mounting element (2, 10, 50, 1000) comprising a means of fastening (4, 12, 53, 102) such as a nut or bolt and an upper washer (14) and a lower washer (16) constituting a pari of washers, where each washer has one side with cams (18, 20) and one principally flat side (22, 24), the washer sides with cams being arranged facing each other. Moreover, the means of fastening includes a principally flat side (26) arranged against a principally flat upper side (22) of the upper washer (14). The said mounting element furthermore includes at least one means of containment (28) arranged to keep together the means of fastening and the pair of washers, whereby the means of containment is allowed a certain axial movement and rotation in relation to the means of fastening or the movement of the pair of washers. The present invention concerns also a means of manufacturing a mouting element and a usage.
