1/2-Inch Hollow-Shank Nut Driver

This Klein Tools 630-1/2 nut driver fits 1/2-inch hex fasteners and features a hollow shank for bolt clearance. A cushion-grip amber handle provides comfort and torque, while the colour-coded cap allows quick size identification. The heat-treated, chrome-plated tempered steel shaft resists wear and corrosion during daily use. It ships new in a single clamshell package.

Technicians needing bolt-through access

The hollow shaft suits electricians and maintenance workers who must drive nuts onto long threaded rods or studs. The standard 3-inch shank length reaches recessed hardware in panels and enclosures. Buyers who require insulated handles for live electrical work should select a different tool rated for that purpose. This model carries a Proposition 65 warning for California users.

Sustained torque on long fasteners

Under continuous turning force the chrome-plated steel shaft maintains its hardness without rounding the hex opening. The cushion grip reduces hand fatigue when driving multiple fasteners in sequence. The hollow design prevents the tool from bottoming out on protruding threads, keeping engagement consistent. The 7-5/16-inch overall length gives ample leverage for stubborn hardware.
