ABSTRACT:
A wrench for turning components such as bolts, nuts, screws or the like wherein a gripping head is pivotally connected to the wrench handle so that with the head gripping the component to be turned, the handle can be pivoted from a position in which it is generally radial with respect to the axis of turning of the component, to a position in which it is more axial relative to the said axis of turning of the component. The wrench preferably has a second gripping head at the other end, and each gripping head is similarly pivoted to the handle. Each head may be pivotable relative to the handle by 90.degree. to each side of a mean position in which the head is in the general plane of the handle.
