Abstract
An open-end wrench for ratcheting increments of 30° has a short clamping jaw supported on a wrench handle so as to be pivotable about a first pivot point. A long clamping jaw is supported on the wrench handle so as to be pivotable about a second pivot point. The short clamping jaw and the long clamping jaw are each pressed into a clamping position by a spring load and can be pivoted into a receiving position against the spring load. In the clamping position, the short clamping jaw and the long clamping jaw reach around a hexagonal object. To pivot into the receiving position, the short clamping jaw is pressed against a sliding surface of the long clamping jaw by the spring load. In the clamping position, an opening width the clamping jaws is more than 55% of the distance between two opposite lateral edges of the hexagonal object.
