The Klein Tools 3/8" hollow-shaft nut driver is built for electricians and panel technicians who need unobstructed pass-through on long bolts and stacked circuit board applications, with a Rare-Earth magnetic tip that captures and holds fasteners securely for one-hand operation in tight enclosures. The full hollow shaft pairs with a premium chrome-plated steel construction to deliver smooth, corrosion-resistant performance through demanding job-site use, while internal handle flanges create a solid, twist-resistant anchor for consistent torque transfer. Tip-Ident® colour coding and a colour-coded handle end make size identification instant in a crowded tool bag or service van.
