Bits have a different tip at each end and snap into the shaft. A ball detent holds the bit in place. To use as nutdriver, remove the bit and turn fasteners with the shaft, which is also reversible.

Ultra-grip drivers have a multicomponent handle that provides comfort and the best possible grip for achieving maximum torque. Those with a voltage detector safely test for AC voltage without contacting live wires. Light and sound indicators alert you when over 50 volts AC is detected. The detector is attached to the tool’s handle; remove it from the handle to use it on its own. Bits turn eight screw sizes and the shaft three external hex sizes.
