7/16 in Hollow Nut Driver

The Klein Tools 630 nut driver fits 7/16 inch SAE fasteners with a three inch hollow shank that clears bolt threads. Its cushion grip handle is coloured yellow with black accents and provides twist resistance during use. The chrome plated handle material adds corrosion resistance for durability in workshop or automotive environments.

Cushion Grip and Non Magnetic Tip

The cushion grip reduces hand fatigue and improves control when turning stubborn nuts or bolts. A non magnetic tip prevents unwanted metal shavings from clinging to the driver during assembly or disassembly tasks. The hollow round shank design allows the tool to slide over protruding studs without bottoming out.

Questions about this item

Will the hollow shank need replacement after heavy use?

The hollow round shank is built from corrosion resistant steel and clears bolts up to 3 in depth for long service life.

What stops me turning the driver continuously on a stuck fastener?

The cushion grip resists twisting so torque transfers to the 7/16 in nut without the handle slipping in your hand.

Does the tool get hot or tiring during all day work?

The cushion grip insulates against conducted heat and reduces hand fatigue during extended use.
