1/2" HollowCore™ Magnetic Nut Driver
48-22-2556
Product Description
The Milwaukee 48-22-2556 HollowCore™ Magnetic Nut Driver is a professional-grade 1/2-inch SAE nut driver designed for installing and removing hex nuts and bolts, especially on long threaded rods and extended fasteners. Its HollowCore™ thread-through shaft allows the tool to slide over long bolts, providing virtually unlimited fastening depth for electrical, mechanical, and construction applications.
The nut driver features a powerful magnetic tip that securely holds fasteners in place, making installation easier when working in overhead or tight spaces. A wrench-ready steel shank allows additional leverage using a wrench for stubborn or high-torque applications.
Built for jobsite durability, the tool includes a forged, chrome-plated steel shaft that resists corrosion and wear. Color-coded markings allow quick size identification, while the ergonomic handle provides comfort and improved control during extended use.
