These innovative wrenches automatically adjust to the correct fastener size. Just place the wrench head over the nut or bolt and squeeze the handles to close the jaws for a snug fit. No more searching for that odd-sized socket.

Each wrench has four toothed jaws that firmly grip hex heads by the flats. Because the jaws are toothed for grip, they can even turn damaged nuts and pipe or tubing.

The small wrench has a capacity of 1/4" to 9/16" (7mm to 14mm) and the large has a capacity of 1/2" to 3/4" (13mm to 20mm) – together, the equivalent of nine SAE wrenches or 14 metric wrenches.
