The "X6" ratcheting combination wrenches incorporate a ratcheting mechanism on the open-end and a static box end. Allows the user to turn nuts and bolts without taking the wrench off the fastener, making jobs faster and easier. The new "X6" wrenches fit six different types of fasteners. They include hex, square, 12-point, external torx, partially rounded hex and spline. Includes sizes of 8, 10, 12, 13, 14, 15, 17 and 19 mm.
