Abstract
A variable adjustable wrench adapted to tighten or loosen nuts and bolts in somewhat inaccessible locations, has a head which is rotatable with respect to the handle such that the angular relationship between the head and handle is variable. A retaining means holds the head in a fixed angular relationship to the handle during the application of a force to a nut or bolt and permits the angular relationship to change while a force is not applied such that a virtually inaccessible nut or bolt can be tightened or loosened by wiggling the handle of the wrench. Means are provided to return the head to the original position after the head has reached its limit of angular travel.
