The toughest bits available, these withstand the shock and twisting force of impact drivers. Also known as insert bits, use with a bit adapter in power tools.

Bits have a knurled shank that allows finger tightening. For more torque, use with the included ratcheting bit screwdriver. They will not fit in standard bit screwdrivers.

A ratchet mechanism allows you to drive fasteners when there's little space to move the handle.

Style E have seven interchangeable bits—all of which are compatible with power tools. Store them inside the handle so they don’t get lost or misplaced when you’re not using them. Bits are held in place by magnets. To use these screwdrivers as a nutdriver, remove the bit and turn fasteners with the shaft.

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. For those without a voltage detector, bits turn four screw sizes and the shaft two external hex sizes. 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.

Cushion-grip drivers offer comfort and some slip resistance. Bits turn eight screw sizes and the shaft three external hex sizes.

When working in tight spaces, these short drivers fit where others can't. 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 and turns two external hex sizes. Drivers have a cushion grip for comfort and some slip resistance.

Press down on the handle’s collar to either adjust the shaft length or remove the shaft and replace it to change the tip. Sets include a handle and multiple reversible shafts. The handle has a contoured ultra grip that provides comfort and the best possible grip for achieving maximum torque.

Additional reversible shafts are sold separately.

The slim body reaches into tight spots to grip and turn screws. Use the magnet at the end of the handle to retrieve dropped fasteners. Screw starters are not intended for final tightening or removal of fasteners.

Starters with wedge tip fit a variety of drive styles. Push the sleeve on the handle forward and insert the tip into screw head. Pull the sleeve back and the tip splits to hold the screw firmly. Once threads are started, the tool releases the screw.

Break stuck screws free using screwdriver bits. Strike the end of the handle with a hammer to turn the bit and tighten or loosen fasteners. Use these tools as an impact wrench without the bit adapter.

These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter. To adjust torque, remove the black vinyl end cap and turn the attached adjustment key. When set torque is reached, the driver slips to disengage and stop turning the fastener, preventing overtightening. Sets come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.

Note: Accuracy ratings do not apply to the lower 20% of the torque range.
