Milwaukee Tool 48-22-2444 Hollowcore Nut Driver Set 4pc

Product Description

The MILWAUKEE TOOL 48-22-2444 is a 4-piece HollowCore nut driver set built for electricians, HVAC technicians, and plumbers who regularly work with threaded rod, conduit fittings, and fasteners. The hollow shaft design allows the driver to pass over continuous threaded rod or long bolts without bottoming out, expanding its use beyond standard fixed-depth applications. Drivers are constructed from steel with a chrome-plated finish for corrosion resistance. The tri-lobe handle provides grip and torque transfer during hand-tightening, and each driver includes a wrench-ready shaft for additional torque when needed. Color-coded markings on the handles allow fast size identification in the field.

This set is suited for residential and light commercial service work across electrical, HVAC, and plumbing trades. Common applications include driving hex-head sheet metal screws, electrical panel hardware, conduit fittings, and equipment mounting fasteners. The hollow shaft is particularly useful in scenarios where fasteners are threaded onto long studs or threaded rod that would otherwise block a solid-shaft driver. The set includes four drivers covering the most common fractional inch nut sizes encountered in trade work.

Key Features

• Hollow shaft allows use over continuous threaded rod and long fastener assemblies
• Wrench-ready shaft hex accepts an open-end or adjustable wrench for added torque
• Tri-lobe handle design improves grip and rotational force during hand driving
• Chrome-plated steel construction resists rust and corrosion
• Color-coded handle markings enable fast size identification without reading labels
• Tether-capable design supports tool-tethering systems for elevated work environments

Compatibility

Designed as a general-purpose fractional inch nut driver set for trade professionals working with 1/4 inch, 5/16 inch, 7/16 inch, and 9/16 inch hex fasteners commonly found in HVAC equipment, electrical panels, conduit hardware, and plumbing fixture assemblies.

Installation Notes

No power source is required for this hand tool set. Electricians and HVAC technicians should de-energize equipment before driving or removing any fasteners on live panels or control assemblies. Note that these drivers are not insulated and are not rated for live electrical work. When using the wrench-ready shaft feature, apply torque carefully to avoid rounding the fastener hex.
