Abstract: A box wrench for stripped nuts, with a handle pivotally connected to a box head having a multi-point gripping ring contour. The gripping ring contour has a fixed major portion of regular points, and a rocker portion on a terminal end of the handle protruding into the box head. The rocker portion defines a minor asymmetric portion of the gripping ring, and is movable between a neutral position aligned with the remainder of the gripping ring, and a grip position misaligned with the remainder of the gripping ring and with an irregular point extended into the space inside the gripping ring to wedge or cam against a stripped nut.
