Milwaukee 49-66-4523 Shockwave 5/16 in Magnetic Nut Driver 3pk

Product Description

The Milwaukee Electric Tool Corp 49-66-4523 is a 3-pack of 5/16-inch magnetic nut drivers from the Shockwave impact-duty line. Each driver measures 1-7/8 inches in shank length and is constructed from high-quality steel for long service life. The magnetic tip securely holds nuts during fastening, reducing dropped hardware in tight spaces. These drivers are rated for use with impact drivers, making them a practical choice for electricians, HVAC technicians, plumbers, and other trade professionals who rely on impact tools for production-speed work.

These nut drivers are suited for residential and light commercial applications where 5/16-inch fasteners are common, including electrical panel work, equipment installation, and mechanical assembly. The impact-duty rating means they are built to absorb the rotational shock produced by impact drivers without premature wear or failure. Sold as a 3-pack, they provide job-site redundancy and are easy to stage across multiple tools or tool bags.

Key Features

• 5/16-inch drive size for standard hex fasteners used across electrical, HVAC, and mechanical trades
• 1-7/8-inch shank length sized for common production fastening tasks
• Magnetic tip holds nuts securely for one-handed installation

Compatibility

Designed for use with standard 1/4-inch hex shank impact drivers and drill/drivers commonly used in electrical, HVAC, plumbing, and general mechanical trade work.

Installation Notes

Insert the 1/4-inch hex shank fully into the impact driver or drill/driver chuck before operating. Confirm the driver bit is fully seated and locked before applying torque. Inspect the magnetic tip and shank for wear or damage before each use, and replace any driver showing cracks or deformation. Follow applicable trade and workplace safety guidelines when working with power tools near energized equipment.
