Description: |
| The overall design is a quick-adjust wrench for hex and square nuts and recessed socket head drain plugs. The rotating collar tightens or loosens a dog which clamps the movable jaw to fine rack teeth on the wrench shank. The collar has an internal slot running its width so a partial turn of the collar releases or engages the dog. The shank is described as square. |
