Klein Tools 5/16-Inch Insulated Nut Driver with 6-Inch Shank

The Klein Tools 646516INS is a 5/16-inch insulated nut driver with a 6-inch shank designed for electrical work in live circuits up to 1000 volts. Each tool is individually tested to exceed IEC 60900 and ASTM F1505 standards and carries the official 1000-volt rating symbol. The hollow shaft design lets you work on stacked circuit boards and long bolt applications where standard drivers can't reach.

Two layers of insulation protect against electric shock - a thick, high-dielectric white inner coating bonded to the tool with a flame retardant, impact-resistant orange outer coating. The Cushion-Grip handle provides better torque and comfort during extended use. Klein's Tip-Ident system makes size identification quick and easy. Made in the USA, this tool meets the requirements for electrical work covered under NFPA 70E workplace safety standards.

A product video is available showing proper inspection techniques for insulated tools. This nut driver fits applications where electrical safety is critical - panel work, control cabinets, and any job where you might encounter energized circuits. The 6-inch shank gives you the reach needed for recessed nuts and tight spaces.
