Improved wrench of the type in which a movable jaw is progressively moved closer or away from another fixed jaw to imprison a nut by two opposed planes of its lateral contour characterized because it has the planes of contact and tightening of one and another jaw forming in each jaw a dihedral of 120º of amplitude so that as each dihedral plane of a jaw is constantly kept parallel to the opposite dihedral plane of the other jaw the said contact and successive tightening on the lateral contour of a hexagonal nut as the most ordinary type is exerted likewise simultaneously on four lateral faces of the nut opposite two to two, one of the two jaws can be displaced and the other fixed.
