Abstract
The apparatus prevents undesirable rotation of screw bolts or the like provided at their ends with spanner working surfaces, in particular large screw bolts. Adapters are positioned individually on the said ends of the screw bolts and each has opposing surfaces adapted to the spanner working surfaces of a screw bolt. Carriers are pushed onto the adapters and each have internal teeth which can be brought into mesh with external teeth of the adapter. A holder mounts least two carriers with slight angular mobility, at a spacing corresponding to the axial interval between screw bolts.
