摘要

The present invention relates to a tool for rotating a rotatable fastener having a round or plural head, such as the example of multi-threaded threaded members, nuts or serds. The tool has a head that can be fitted or fitted to a rotatable material, the head extending substantially transverse to the centerline of the inner and inner openings receiving the fastening material and movable transversely to the centerline of the inner opening. It has at least one hole in which the material with the tapered front side at one point in the inner opening direction can be removed or placed. It is preferred that there are two holes which are disposed diametrically opposite to each other with respect to the centerline of the inner opening and in which the individual material having a sharp front end in each of them can be removed or placed. Fastenings that can carry large loads can be achieved by tightening the pointed moving materials against the fastening material to be loosened, so that completely round and / or very tightly held screws, screw bolts, nuts or the like Even others, can be surely loosened.
