No. 0 Hex Drivers | McMaster-Carr

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.

The handle on these assorted ESD-safe screwdrivers drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. They meet IEC 61340-5-1 requirements for protecting electronic devices from electrostatic discharge. Press the rotating end cap on the handle to apply constant pressure with your palm while turning the body of the screwdriver with your fingertips.

Warning: Because the handle conducts electricity, screwdrivers must not come in contact with sources of electrical power.

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.
