Milwaukee 48-22-2521 1/4 in. Magnetic HollowCore Nut Driver

The Milwaukee 48-22-2521 1/4 in. Magnetic HollowCore Nut Driver is engineered for fast, secure fastening wherever hex nuts and bolts need to be run down quickly and accurately. Sized at 1/4 in., this nut driver features Milwaukee HollowCore shaft design, bored straight through the tool so it can slide directly over long bolts, screws, threaded rod, and all-thread without the fastener needing to be trimmed to length first. A magnetic tip at the working end grips fasteners on contact, holding them steady for confident one-handed starts even when working overhead or inside tight enclosures. Whether it is used for electrical panel assembly, conduit and fitting hardware, or general mechanical fastening, the Milwaukee 48-22-2521 is built to help professionals move through repetitive fastening tasks with fewer dropped fasteners and less downtime on the jobsite. This driver is equally at home in an electricians tool pouch or a maintenance techs toolbox, keeping repetitive fastening tasks moving without swapping tools.

Key Features

• Trade Size: 1/4 in. drive size fits standard hex fasteners for panel, enclosure, and equipment assembly work.
• HollowCore Shaft Design: The hollow-core construction runs the full length of the shaft, allowing the driver to pass over long bolts, screws, and threaded rod without cutting the fastener down first, which saves time on repetitive tasks.
• Magnetic Tip: A built-in magnetic tip grips fasteners securely, reducing dropped hardware and speeding up one-handed starts in tight, overhead, or hard-to-reach spaces.
• Compact, Purpose-Built Driver: Sized specifically as a 1/4 in. nut driver for quick, repeatable access to hex nuts and bolts in electrical, HVAC, and general maintenance applications.
• Efficient One-Handed Operation: The combination of the HollowCore shaft and magnetic tip lets users start and run fasteners without repositioning hardware or switching tools mid-task.
• Dedicated 1/4 in. Sizing: A single, purpose-built 1/4 in. size keeps this driver ready for repeat use on common hex fastener sizes without needing a full driver set on hand.
