Electrical-Insulating Nutdriver Sets

External Hex

The assorted drivers in these sets have an insulated handle and shaft that protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet IEC 60900 and ASTM F1505. The shaft and handle are drilled all the way through, enabling turning of nuts on any length of threaded rod. Drivers are color-coded by size. They have a cushioned grip for comfort and some slip resistance.

Nutdriver Bits

Hex Shank for Power Tools

External Hex

Also known as nut setters, these bits turn hex nuts and cap screws.

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.
