Bit Assortments

These assortments contain general-purpose bits.

Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.

Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Tight-Clearance Screw Starters

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.

Torque Screwdriver and Bit Sets

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.
