Klein Tools 640-1/2 1/2 x 7-5/16 Inch Plastic Handle Red Coated Hollow Shaft Nutdriver

The Klein Tools coated nut driver tightens nuts and bolts easily and can get into smaller spaces that wrenches and ratchets can't reach. It makes wood, metal and electrical work easier in confined spaces. The full hollow shaft facilitates work on stacked circuit boards or other long bolt applications.
