Milwaukee Tool 48-22-2548 Metric Nut Driver Set 7 Pc

Product Description

The MILWAUKEE TOOL 48-22-2548 is a 7-piece metric nut driver set built for trade professionals who work with fasteners in HVAC, electrical, and plumbing service applications. Each driver features a hollow-core steel shaft that accommodates long bolts and threaded rod, eliminating the need to stop and reposition. The tri-lobe handle design provides a secure grip and high torque transfer. Magnetic tips hold fasteners securely during installation. Sizes range from 5 mm through 13 mm, covering the most common metric hex head fasteners found in equipment panels, terminal blocks, and sheet metal assemblies. Shaft length is 4 inches with an overall length of 10.43 inches per driver.

This set is suited for residential and light commercial service work where metric fasteners are common, including HVAC equipment installation and servicing, electrical panel work, and appliance repair. The hollow shaft design is especially useful when driving nuts onto long machine screws or all-thread rod without removing the fastener. Chrome plating on the shafts provides rust resistance in humid or outdoor environments. Color-coded markings on each driver allow quick size identification when working from a tool pouch or bag. The set does not include a storage container.

Installation Notes

No power source is required for hand tool use. When using the wrench-ready shaft feature, select an appropriately sized open-end wrench and apply steady torque to avoid rounding fastener heads. Inspect the magnetic tip periodically for debris buildup that can reduce holding force. Store drivers in a dry location to preserve chrome plating and shaft integrity.
