Milwaukee 49-66-4705 3/8 Inch Magnetic Nut Driver

Product Description

The Milwaukee Electric Tool Corp 49-66-4705 is a Shockwave Impact Duty magnetic nut driver designed for use with 3/8-inch fasteners and built to a 1-7/8-inch length. Engineered for high-torque impact driver applications, this nut driver features a magnetic tip that retains nuts and hex fasteners during installation. The Shockwave design absorbs peak torque from impact drivers, extending the working life of the bit and reducing fatigue on the fastener. It is sold in a package of 10 units, making it practical for stocking service vehicles and job site kits. HVAC technicians, electricians, plumbers, and general trade professionals use this driver for panel work, sheet metal fastening, and equipment installation.

This nut driver is suited for use in residential and light commercial trade applications where 3/8-inch hex fasteners are common. Typical uses include securing electrical panels, HVAC cabinet screws, conduit fittings, and plumbing access covers. The magnetic retention tip helps prevent dropped fasteners in tight or overhead spaces. The 1-7/8-inch overall length provides clearance for most standard fastener depths in trade service work. Packaged in a quantity of 10, this SKU supports crew stocking and wholesale replenishment needs.
