1/4-Inch Nut Driver 6-Inch Shaft

This Klein Tools nut driver is built for fastening 1/4-inch SAE hardware. The 6-inch hollow shaft provides bolt clearance for longer threaded rods or studs. A cushioned grip improves comfort during repetitive use. The non-magnetic tip prevents unwanted metal shavings from clinging to the driver.

Hollow Shaft Build Fit

The hollow round shank slides over protruding threads so you can drive nuts without removing the bolt first. This clears space in tight engine bays, electrical panels or machinery where standard solid-shank drivers cannot reach. The 6-inch length adds leverage while keeping your hand clear of hot or sharp components.

Hand Tool Thermals Noise Power

As a manual hand tool, it generates no heat, noise or electrical draw during operation. The cushion grip insulates against conducted vibration from impact drivers if used with a power adapter. No batteries, fuel or compressed air are required so there are no operating costs or emissions.
