9 mm High-Torque Nut Driver (Previous Version)

Uniquely designed, the handle is a versatile combination of torque and speed. Its three-sided geometry engages the structure of your hand, not just friction against your skin, to turn the driver. This means you can comfortably apply much more force, even when your hand is greasy or tired. For long, finely threaded fasteners, round top and bottom sections allow your fingertips to spin the driver quickly and smoothly.
