Description: |
| The wrench adjusts by turning the end of the handle. The movable jaw has a squared shank sliding in a squared recess in the frame of the fixed jaw. The main focus of the patent is for the tube that extends through the base of the fixed jaw, the tube's connection to the adjusting handle, and related features. The jaws have flat and obtuse angle sides for square and hexagonal nuts. |
