Klein Tools® 5/16" x 3" Hollow Shank Nut Driver
This nut driver is standard length for most applications and fits over long bolts and studs. The full hollow shaft facilitates work on stacked circuit boards or other long bolt applications, and the internal flanges provide solid, twist-resistant shaft anchor. Premium chrome plating for smooth feel and corrosion resistance. The handle end is also color coded for easy identification, and the cushion-grip handle allows for greater torque and comfort.
