Abstract

The nut has a central and axial threaded hole (7) for a threaded bar. A number of discs (1) rest on the outside of the conical nut (2) whose first end has a smaller periphery than the second end (6). The conical nut is movable axially in the discs. The end of the discs facing the second end of the conical nut carry a thrust-piece (4) gripping over the conical nut from outside for axially supporting the threaded bar.
