摘要： A wrench for turning locknuts has a C-shaped head pivotally attached by an extension member to a handle. A recessed step extends part-way around an interior arc of the head, and has a radius sufficient to receive the overall diameter of a locknut. The recessed step is terminated by a shoulder at the end of each arcuate arm forming the head; the shoulders extend toward the center of the head and have dimensions and spacing to fit into the spaces between lugs on a locknut. A notch has a common distal boundary with the recessed step and provides free play in the fit of the wrench over a locknut. When the wrench is placed over a locknut the shoulders fit between and engage lugs on the locknut for turning.
