Klein Tools has expanded the Insulated Nut Driver product line to include nine new insulated nut drivers with 6" shafts, as well as two new nine-piece driver kits available in either 6" shafts or 3" and 4" shafts. The 6" insulated drivers have a full hollow shaft that allows for work on long bolt applications, allowing full engagement with the nut to hold fasteners securely in place. It also provides additional distance from energized sources, especially when working on stepped blocks within panel blocks. Two layers of insulation provide protection against electric shock, and a feature patented Tip-Indent with color codes allows for quick identification of nut driver and size. A Cushion-Grip handle allows for greater torque and comfort.
