A wrench is configured to rotate a fastener. The wrench includes a handle and a head pivotally coupled to the handle. The head includes a first jaw configured to engage the fastener and a second jaw configured to engage the fastener. The second jaw is movable with respect to the first jaw to adjust a distance between the first jaw and the second jaw. The wrench also includes an actuator operable to move the second jaw with respect to the first jaw to adjust the distance. The handle is pivotally coupled to the head such that rotation of the handle with respect to the head moves the second jaw toward the first jaw. |
