<p>A folding multifunction wrench (120) for tightening or loosening a plurality of different sized rotary fasteners, comprising at least two wrench heads (121, 122, 123, and 124) attached to their own respective wrench arm (125, 126, 127, and 128) with the wrench arms pivotally mounted together at a hinge (130) and pivotal (foldable) to a smaller stowed position or extend to a larger operational position. Individual wrench arms can be used either as a wrench handle or as a wrench tool depending on which end of the wrench the user grasps. During use the rotational axes of the gripping surfaces on the wrench head can be oriented within ten degrees of being perpendicular to the hinge axis of the two or more wrench arms, whereby torque can be transmitted across the hinge axis for turning the plurality of different sized rotary fastener.</p> |
