Milwaukee 49-66-4736 Shockwave Magnetic Nut Driver 7/16 in

Product Description

The MILWAUKEE 49-66-4736 is a SHOCKWAVE Impact Duty magnetic nut driver designed for use with power impact tools in demanding trade applications. Built from proprietary steel and heat-treated for controlled hardness, it delivers up to 10 times the service life of standard nut drivers. The 7/16 inch drive size and 2-9/16 inch length make it well suited for fastening in confined spaces. A powerful internal magnet provides a secure grip on fasteners, keeping the nut seated during drive. Licensed electricians, HVAC technicians, and plumbers reach for this driver when running sheet metal screws, equipment panels, and conduit fittings.

This nut driver is intended for use in residential and light commercial service work where speed and bit longevity matter. The chamfered edge allows access in tight clearances common when securing electrical panels, HVAC cabinet covers, and mechanical equipment enclosures. Color-coded size rings allow techs to grab the correct driver at a glance without stopping to read the shank, reducing errors during fast-paced installs.

Installation Notes

This nut driver is installed and used by electricians, HVAC technicians, plumbers, and general mechanical contractors.
