Nut Drivers

A nut driver is a socket fixed to a handle and turned like a screwdriver. It is quicker than a ratchet for a run of low-torque fasteners; anything needing real torque belongs on a socket set. T-handle and straight patterns are listed here in metric sizes.

Where a nut driver beats a ratchet

A nut driver fixes the socket straight onto a handle or a bar. With no ratchet mechanism it is slim and light, and on work with many low-torque fasteners in a row -- die changes, panel building, furniture assembly -- it is quicker than a ratchet.

The double-ended nut drivers here are made from seamless steel tube and zinc plated, with a different size at each end. A tommy bar through the tube turns it, so the effective handle length is whatever the job needs.

Where its limit is

The thin body limits the torque it can carry. Forcing a seized fastener with a nut driver ovalises the tube; move to a socket set when real torque is needed.

The tommy bar is listed separately too, so a lost or bent bar can be replaced without replacing the wrench.

Frequently Asked Questions

  • How does a nut driver differ from a socket?

    A nut driver's socket is fixed to the handle or tube; a socket fits a ratchet. The nut driver is faster on low-torque repeat work, the socket carries the torque.

  • Can I free a seized bolt with a nut driver?

    No. The thin tube ovalises and the tool is finished. Use a socket set on a seized joint.

  • Can I buy the tommy bar separately?

    Yes, the bar is listed as its own product, so a bent or lost one is replaced without replacing the wrench.
