Milwaukee Tool 48-22-2561 5mm Hollow Shaft Nut Driver

Product Description

The MILWAUKEE TOOL 48-22-2561 is a 5 mm hollow-shaft nut driver built for trade professionals who need reliable fastener control in tight or repetitive-drive applications. The hollow shaft allows the driver to seat over long threaded studs or bolts without bottoming out, keeping the tool fully engaged throughout the drive stroke. A built-in magnet holds fasteners securely during placement. The steel shaft features a chrome finish for corrosion resistance, and the tri-lobular handle delivers a firm, slip-resistant grip during high-torque turns. Overall length is 7.2 inches, and the tool weighs 0.238 pounds.

This nut driver is suited for residential and light commercial service work across HVAC, electrical, and plumbing trades. It excels in panel work, equipment installation, and service calls where 5 mm hex fasteners appear on terminal blocks, access panels, and component mounting hardware. The hollow shaft design is especially useful when driving fasteners onto extended threaded rod or long machine screws common in equipment installations.

Installation Notes

Nut drivers are a hand-tool installation and not trade-licensed for installation themselves, but they are standard equipment for licensed HVAC technicians, electricians, and plumbers. Always de-energize electrical panels and equipment before servicing fasteners near live conductors. Inspect the shaft and handle for cracks or damage before use, and do not use this tool as a substitute for an insulated driver when working near energized components, as this driver is not rated for insulated use.
