Milwaukee Tool 48-22-2544 Magnetic Nut Driver Set 4 Pc

Product Description

The MILWAUKEE TOOL 48-22-2544 is a 4-piece hollow-shaft magnetic nut driver set designed for fastening and driving hex-head fasteners in HVAC, electrical, and general mechanical service work. Each driver features a HollowCore shaft that accepts long bolts and threaded rod to pass through, extending reach and versatility on confined fastening applications. Drivers are magnetic for secure fastener retention during placement. The set covers four fractional inch sizes spanning 1/4 inch through 9/16 inch, handling the most common hex-head fastener sizes encountered in field service. Overall length measures 7.17 inches with a 3-inch shaft, and total set weight is 1.168 pounds.

This set is suited for residential and light commercial HVAC installation and service, electrical panel work, appliance repair, and plumbing fixture work where hex-head screws and sheet metal fasteners are common. The tri-lobe handle profile provides grip in both wet and dry conditions. Color-coded handle markings allow quick size identification without reading the shaft stamp, which is practical in low-light service environments such as equipment closets and air handler compartments.

• Tether-capable design supports tool tethering for elevated or drop-risk work areas

Compatibility

Designed for use with standard fractional-inch hex-head fasteners in the 1/4 inch to 9/16 inch size range. Suitable for HVAC equipment, electrical enclosures, and mechanical assemblies using 1/4 inch, 5/16 inch, 7/16 inch, and 9/16 inch hex-head fasteners.

Installation Notes

Nut drivers should be used by hand only unless the wrench-ready shaft flat is engaged with an open-end wrench for additional torque. De-energize electrical equipment and lock out power before using hand tools in or near live panels or control boxes. Inspect the magnetic tip for metal debris before use to avoid cross-threading fasteners. These drivers are not insulated and are not rated for live electrical work.
