Milwaukee 49-66-4735 Shockwave Magnetic Nut Driver 3/8 in

Product Description

The MILWAUKEE 49-66-4735 is a SHOCKWAVE Impact Duty magnetic nut driver built for use with power impact drivers in demanding trade applications. Sized at 3/8 inch with an overall length of 2-9/16 inches (approximately 2.56 inches), this nut driver is machined from proprietary steel and heat-treated for controlled hardness. The result is a driver rated for up to 10 times the service life of standard nut drivers under impact loads. A high-strength magnet provides secure fastener retention during installation. Electricians, HVAC techs, plumbers, and general contractors working with power tools will find this driver a reliable daily-use bit.

The 49-66-4735 is designed for use with 3/8 inch hex fasteners in both residential and commercial service work. The chamfered edge on the drive end allows fastening in confined spaces where a standard driver cannot reach or seat cleanly. The color-coded identification ring on the shank allows technicians to quickly pull the correct size from a pouch or tool bag without stopping to read markings. Typical applications include equipment panels, electrical enclosures, HVAC access covers, and mechanical fasteners encountered during routine service calls.

Key Features

• Proprietary steel construction with impact-specific heat treatment for up to 10X longer life versus standard nut drivers
• High-strength magnet for secure fastener grip and positive bit engagement during driving
• Chamfered drive edge for fastening in tight or obstructed spaces
• Color-coded size identification ring for fast visual selection in the field
• 3/8 inch drive size covering common hex fastener applications across trades

Compatibility

Designed for use with 3/8 inch hex fasteners and compatible with impact drivers and drills accepting standard 1/4 inch hex shank accessories. Suitable for use across trade applications requiring impact-rated nut driving performance.

Installation Notes

Install and remove this driver with the power tool unplugged or the battery removed before handling. Seat the shank fully into the tool chuck before applying torque. This driver is rated for impact use — do not use in a manual screwdriver handle or ratchet. Inspect the drive tip and magnet for wear before each use and replace if the hex profile shows rounding.
