The Klein Tools 823018-INS is a 3/8-inch insulated hollow-shaft nut driver built for demanding professional applications. The full hollow shaft accommodates long bolts and stacked circuit board work, while internal flanges deliver a solid, twist-resistant shaft anchor. Premium chrome plating ensures a smooth feel and lasting corrosion resistance, and the tool meets or exceeds applicable ASME/ANSI specifications.
Designed for comfort and efficiency, the cushion-grip handle provides greater torque and reduces hand fatigue during extended use. The handle end is color-coded for quick size identification, and Klein's patented Tip-Ident feature lets you instantly recognize the nut driver and its size at a glance — keeping your workflow fast and organized.
