You can never have too many tools in your box, and the Craftsman 4-in-One wrench set features two reversible ratcheting box wrenches that combine four standard sizes into each wrench for a total of eight fitments: 5/16 x 3/8-inch, 7/16 x 12-inch, and 9/16 x 5/8-inch, 11/16 x 3/4-inch. The heat-treated handles are available in nickel-chrome plating or black electro-coated finishes.
