An adjustable wrench including a handle and a fixed jaw and a movable jaw disposed at one end of the handle. Two opposite sides of the two jaws respectively have a clamping face. At least two types of tooth regions are formed on the clamping face of at least one of the jaws. The tooth regions include a fine-tooth region composed of multiple fine teeth near inner end of the jaw and a coarse-tooth region composed of multiple coarse teeth near outer end of the jaw. When wrenching a small-size worn nut, the fine teeth of the fine-tooth regions of the jaws serve to clamp the nut. When wrenching a large-size worn nut, the coarse teeth of the coarse-tooth regions of the jaws serve to engage the nut.
