Not for: Shops working mainly in SAE sizes.
What the AI looks for in Nut Drivers
- Hollow shaft depth
- Choose full-length hollow shafts for bolts and threaded rod that stick out past the nut. A solid shaft bottoms out on protruding studs.
- Size system
- Match SAE or metric to your fasteners. 1/4, 5/16 and 3/8 inch cover most appliance and HVAC hex screws. A near-fit size rounds hex heads.
- Magnetic tips
- Magnetic sockets help with sheet-metal screws, but avoid them near sensitive electronics. Magnets hold the fastener, which matters when working overhead.
- Insulation rating
- Use drivers certified to IEC 60900 for work inside live panels. Nut drivers are often used in electrical enclosures.
Brands that matter
- Klein Tools: Standard choice for electricians and HVAC technicians.
- Wiha: Metric and insulated options.
- Wera: Well-made nut spinners with ergonomic handles.
What to avoid
- Shallow-socket sets if you work on threaded rod or long bolts
