| 摘要 |
A wrench including an inward opening that has a multi-point configuration for partially-surrounding engagement in a torque-transmitting manner on a polygonal profile of a nut or a bolt head, a radial jaw opening being associated with the inward opening and at least two corners of the multi-point configuration each having a stop for a portion of an end face of the polygonal profile. In order to extend the range of use of the wrench, the jaw opening has oppositely-disposed jaw cheeks as the opening of an open-end wrench for torque-transmitting engagement on the polygonal profile, the jaw cheeks extending over the corners of the multi-point configuration on only one wide face (of the wrench).
