A system, comprising a nut (1) with a thread (8), and a washer (2) which is configured in a rotationally symmetrical manner and has a cross section substantially in the form of a circular ring, and which narrows inwardly in longitudinal section such that the axial height of the inner side of the washer (2) is less by a given height g than the axial height of the outer side of the washer (2), is intended to ensure particularly uniform distribution of forces over the height of the thread while being easy to produce technically. To this end, the height g is less than 0.2* (s-d) *H1/h, wherein s is the width across flats, d the nominal thread diameter, h the height and H1 the flank coverage of the thread (8) of the nut (1).
