7/16 inch nut driver with hollow shaft

This Klein Tools nut driver is a hand tool designed to drive or remove 7/16 inch hex nuts and bolts. Its hollow shaft allows the fastener to pass through when working on long threaded rods or studs. The 6 inch shank provides reach into recessed areas. The overall length is 10-5/16 inches.

Suited for maintenance

Mechanics and technicians who need to access fasteners in deep or obstructed locations will find the long shank useful. Users requiring an insulated handle for electrical work or a different drive size should look at other options. The fixed 7/16 inch socket means it cannot adapt to other fastener sizes.
