Nut Drivers

Nut drivers are hand tools used to tighten, loosen, and adjust compatible hex nuts and fasteners. Commonly used by maintenance professionals, electricians, technicians, and assembly teams, they provide screwdriver-style control for everyday fastening work, including applications involving long studs, extended bolts, recessed fasteners, or obstructed access points.

Choose Nut Drivers for the Fasteners and Access Challenges You Face

The available nut drivers include individual tools and sets in hollow-shaft and flexible-shaft designs. Start by confirming the fastener size and whether the job calls for a straight path to the nut, clearance over a long bolt or stud, or a route around obstructions.

Use Cases

Manual fastening and adjustment

Nut drivers provide hand-operated control for tightening, loosening, and adjusting compatible hex nuts and fasteners in maintenance, electrical, assembly, and shop work.

How to Choose

Match size and shaft design

Select a driver that matches the compatible fastener size, then choose hollow shaft clearance for long bolts or studs or a flexible shaft for access around obstacles.

Applications

Work in tight or extended locations

Hollow-shaft tools support work on extended fasteners and stacked circuit boards, while flexible-shaft tools help reach metric fasteners in obstructed areas.

Additional Information

Consider identification and handling

Sets keep multiple sizes together. Color-coded or marked ends can help identify sizes quickly, and cushion-grip or molded handles provide a comfortable handhold for manual turning.

Planning Guide

Plan the right fit before choosing

Start with the fastener

Confirm the size system and required driver size

Choose an individual driver when one recurring fastener size is needed, or select a set when work involves several sizes. The represented options include inch sizes such as 3/16 in., 5/16 in., 11/32 in., 7/16 in., and 1/2 in., plus metric flexible-shaft sizes from 5 mm through 10 mm.

  • Use inch-size drivers for compatible inch hex fasteners.
  • Use metric drivers for compatible metric hex fasteners.
  • Choose a multi-piece set for coverage across several commonly used sizes.
  • Look for marked or color-coded ends when quick size identification is useful.
Choose access style

Use hollow shafts for extended fasteners and flexible shafts for obstructions

A hollow shaft allows the tool to fit over long bolts and studs, helping with recessed or extended fastening locations. Flexible shafts help guide the socket around obstacles where a straight tool cannot easily reach the fastener.

  • Hollow shafts accommodate nuts on long bolts or studs.
  • Full hollow shafts can support work around stacked circuit boards.
  • Flexible shafts help access fasteners positioned around obstructions.
  • Deep recessed sockets provide clearance for studs extending through a nut.
Consider handling and reach

Match the tool to the work position

Cushion-grip and molded screwdriver-style handles offer a comfortable handhold for controlled manual turning. Some flexible-shaft drivers have a 265 mm overall length for extended reach, while one hollow-shaft driver has a 9-inch overall length and a seven-piece set has consistent 3-inch shafts.

  • Cushion-grip handles support comfortable handling and torque control.
  • Molded handles provide a familiar screwdriver-style grip.
  • Extended overall length can help access recessed fasteners.
  • Consistent shaft lengths can simplify use across a set.
