Built for the demands of professional electricians and contractors, the Milwaukee® SHOCKWAVE Impact Duty™ 1/4" x 2-9/16" Magnetic Nut Driver (49-66-4532) is engineered to perform in the toughest job-site conditions. Whether you're driving screws into electrical panels, securing conduit fittings, or working overhead in tight spaces, this nut driver delivers the durability and control tradespeople rely on. The SHOCK ZONE™ absorbs peak torque from impact drivers, preventing breakage during heavy-duty applications, while the Most Durable Magnet holds fasteners securely in place during set-up — eliminating fumbling and dropped hardware on the job. Colour-coded bands make it easy to grab the right size at a glance, and the improved hex geometry ensures a precise fit with reduced stripping. Compatible with both impact drivers and drill drivers, this is the nut driver built to last the life of your tool.
