Description: |
The adjustment on the movable jaw is a screw with two "disks" that engage rack teeth on the main bar. The disks are cut away on one side to allow free movement, and the thread pitch on the screw is coordinated with the rack teeth spacing to allow for adjustment to any size of nut that will fit between the jaws. This is a fairly simple means to obtain a combination quick and screw-adjust nut wrench. |
