The MILWAUKEE 49-66-4567 is a 6-piece, 6-inch magnetic nut driver set engineered for impact tool use. Built under the Shockwave Impact Duty line, these drivers are designed to absorb and redirect the torque output of impact drivers, reducing breakage and extending tool life. The magnetic tips retain fasteners securely during overhead and confined-space work. Licensed tradespeople working in electrical, HVAC, plumbing, and general mechanical service will find this set suited to high-demand jobsite conditions.
This nut driver set is intended for use with cordless and corded impact drivers in both residential and light commercial applications. Common install scenarios include panel work, equipment fastening, conduit fitting, and equipment access panel reassembly where a range of hex nut sizes is needed. The 6-inch length provides clearance over deeper fasteners and extended reach in tight mechanical bays.
Designed for use with standard 1/4-inch hex shank impact drivers and drills. Suitable for general trade use across electrical, HVAC, and mechanical service applications.
Nut drivers should be seated fully into the impact driver chuck before use to prevent slippage under torque. Inspect driver tips for wear or rounding before each use session. These drivers are intended for impact tool use; avoid using them with manual-only drivers in applications requiring precise torque control without an impact mechanism. Store in the included case or a designated hand tool organizer to prevent tip damage.
