Unique, versatile design allows wrench to be used with or without optional handles. Tubular wrenches may be used without the handle to quickly run down nuts. The handle can then be attached to provide maximum turning power for final tightening or to reach otherwise inaccessible fasteners. A detent on the wrench shaft helps to align locking button with handle hole. Open end wrench head provides access in tight areas. Sizes of both SAE and corresponding metric fasteners are shown
