Purpose-built for electrical work on energized components, this 7-piece insulated nut driver set is rated for 1000 V AC and individually tested to 10,000 V AC. The kit contains 3/16" (4.8 mm), 7/32" (5.6 mm), ¼" (6.4 mm), 5/16" (7.9 mm), 3/8" (9.5 mm), 7/16" (11.1 mm), and ½" (12.7 mm) drivers with cushion grip handles molded directly to the blades for a permanent bond. To prevent the tools from rolling off flat surfaces, each handle includes parallel flats and is sized proportionately to the blade for consistent mechanical advantage.
