Check out the hollow shaft design with Rare Earth magnetic tip.

Hollow shaft facilitates work on bolt applications.

Klein's new 3 Inch Magnetic Cushion Grip Nut Drivers will reach into deep recesses and fit over extra-long bolts and studs to tighten and loosen fasteners.

The handle domes are color coded by size.

Plus, they feature Klein's patented Tip-Ident that shows the actual hex-head shape and size in fractional inches, so it's easy to locate the needed size in a pouch full of tools.

The Cushion-Grip handle makes it possible to deliver more turning power with less discomfort.

The sturdy hollow steel shaft is heat treated, then chrome plated, and features integral flanges solidly anchored into the rugged plastic handle for a torque-resistant connection.
