Seven-piece nut driver set

The Klein Tools 409-631 set contains seven nut drivers with 3-inch shafts. Sizes range from 3/16 inch to 1/2 inch in standard fractional increments. Each driver has a cushion grip handle for comfort and torque. The set is supplied new and ready for immediate use.

Technicians needing common fastener sizes

Maintenance technicians and electricians who regularly work with 3/16 through 1/2 inch hex nuts will find every size they need in one pack. Users who require metric sizes, shorter shafts for tight cavities, or hollow shafts for threaded rod should look at other configurations.

3-inch shaft length on every driver

All seven nut drivers share a uniform 3-inch shaft length, which determines reach into recessed hardware. If the application demands longer reach or a shorter profile, this set will not fit the task.

Questions about this item

What shaft length do the 3/16-inch through 1/2-inch nutdrivers share?

Every driver in the set has a 3-inch shaft, giving consistent reach across the seven sizes.

How are the cushion-grip handles attached to the shafts?

The handles are permanently fixed; the set is ready to use straight from the package with no assembly required.

When should a nutdriver be replaced?

Replace any driver if the hex opening rounds out, the shaft bends, or the cushion grip splits and loses grip.
