The DeWalt 21MM Combination Wrench (DWMT75193OSP) has a long panel design that provides more reach and the ability to apply more torque with less force. It was built to last, featuring a durable full polish chrome vanadium finish with stamped markings for easy identification of size. A stamped hashmark pattern on the wrench handle provides additional grip points and a 13 degree offset box end provides additional knuckle clearance. The wrench also features a fifteen degree offset opening that allows for an increased arc of swing and integrated Direct Torque technology helps to prevent the rounding of fasteners during high torque applications.
