Milwaukee 49-66-4522 Magnetic Nut Driver 3-pack Impact

Product Description

The Milwaukee Electric Tool Corp 49-66-4522 is a 3-pack of 0.25-inch magnetic nut drivers from the Shockwave impact-duty line. Each driver measures 0.25 inches by 1.875 inches and is constructed from high-quality steel for long-term durability under heavy use. The magnetic tip retains nuts during fastening, reducing fumbling in tight spaces. These drivers are rated for use with impact drivers, making them suitable for electricians, HVAC technicians, plumbers, and other trade professionals who rely on impact tools for speed and torque on the job site.

These nut drivers are intended for trade and construction applications where 0.25-inch fasteners are common. Typical use cases include panel work, equipment installation, ductwork, and general mechanical assembly. The impact-duty rating means they can be run continuously in a power impact driver without the premature cracking or stripping that affects standard nut drivers under impact loads. The 3-pack format reduces downtime from misplaced drivers on active job sites.

Key Features

• Impact-duty rated for use with power impact drivers
• Magnetic tip holds nuts securely during installation
• 0.25-inch drive size for standard fastener applications
• 1.875-inch overall working length
• High-quality steel construction for durability under repeated impact
• 3-pack format reduces loss risk on active job sites

Compatibility

Designed as an OEM-spec replacement and standard accessory for 0.25-inch hex-shank impact drivers and drill drivers commonly used in electrical, HVAC, plumbing, and general mechanical trade work.

Installation Notes

These nut drivers are installed as accessories into any 0.25-inch hex-shank impact driver or drill driver. Ensure the shank is fully seated in the tool chuck before operation. When working near energized panels or equipment, follow NFPA 70E arc-flash and shock-hazard protocols and confirm power is isolated before fastening hardware on electrical assemblies. Inspect the magnetic tip periodically for metal particle buildup, which can affect retention performance.
