ABSTRACT:
An adjustable wrench particularly suited for use on six-sided fasteners. The wrench has a handle that mounts two adjustable arms that each have a gripping head formed on an end portion that projects from the handle. The handle has a fixed flat surface on its top end located between the two projecting arms. The wrench includes a mechanical arrangement to move the arms into and out of a gripping relationship with the fastener. The arms are positioned with respect to the handle and the flat surface so that the flat surface and gripping surfaces of the gripping heads are in an abutting relationship with the associated fastener sides regardless of its size. This three-sided contact on the fastener results in an equiangular distribution of force exerted upon the fastener.
