The Klein Tools 32809MAG 9-in-1 Pass Through Magnetic Nut Driver is the versatile, space-saving fastening tool that electricians, contractors, and serious DIYers reach for when working with hex nuts, bolts, and threaded rod on the job site. Nine SAE sizes in a single tool — from 3/16 to 3/4 inch — eliminate the need to carry a full set of individual nut drivers, while the pass-through handle and barrels allow fastening onto threaded rod of any length without bottoming out. Strong rare-earth magnets securely hold smaller nuts and bolts for one-handed driving, and a spring coil retains larger sizes where magnets aren’t used. An extended wrench-assist on each barrel delivers extra torque when breaking loose stubborn fasteners, and colour-coded bands make size identification instant even in low-light conditions. The heavy-duty Cushion-Grip™ handle provides the comfort and grip needed for extended use in panels, enclosures, and structural applications.
