Features

Seven sizes in one tool allow for easy, one-handed driving

Spring coil (7/16-Inch, 9/16-Inch) holds nuts and bolts in place without the use of magnets

Heavy-duty handle and shaft exceed the torque performance of regular nut drivers

Wrench-assist on handle for added torque on tough jobs

Color-coded bands for easy identification
