A wrench for gripping a rotary fastener, includes: a main body including a handle and a C-shaped head portion that is formed with parallel first and second holes; a first gripping element being resiliently movable in the first hole; and a second gripping element being resiliently movable in the second hole. When the main body is rotated clockwise, the rotary fastener is clamped between the first and second gripping elements and is rotated together with the main body. When the main body is rotated counterclockwise, the first and second gripping elements are moved resiliently by the rotary fastener to be separated from the rotary fastener. |
