Milwaukee's new 7-in-1 Hollowcore Multi-Nut Driver promises 'unlimited depth' for threaded rods, a direct solution to a common job site frustration. This 2026 tool features a HOLLOWCORE™ shaft, allowing fasteners to pass through completely for deep-set applications, according to Milwaukee Tool. While tradespeople typically juggle multiple nut drivers for various fastener types and depths, this single tool consolidates 1/4” through 3/4” HOLLOWCORE™ nut drivers and fits Square, 12 point, 8 Point, and HEX fasteners, according to A Concord Carpenter. Professionals will likely see increased efficiency and less toolbag clutter, potentially redefining multi-nut driver design. The driver also includes a wrench-ready shank for added leverage, a feature highlighted by Milwaukee Tool.
Beyond the Multi-Driver: Comprehensive Hollowcore Offerings
Milwaukee offers more than just the 7-in-1 multi-driver. Dedicated 7-piece SAE HOLLOWCORE Nut Driver sets (1/4" to 9/16", including 11/32") are available for $48.99, according to Tool Nut. A 7-piece Metric HollowCore Nut Driver set (5mm to 13mm) is also offered, according to Milwaukee Tool. All these drivers feature the HOLLOWCORE Shaft for unlimited depth in threaded rod applications.
The 7-in-1 multi-driver includes 3/4" but omits 11/32", a size present in the dedicated SAE set. This difference forces tradespeople to choose between consolidated convenience and specialized, comprehensive coverage. However, offering both metric and SAE sets, alongside competitive pricing, ensures professionals can access the Hollowcore advantage across diverse applications and budgets.
How Milwaukee's Hollowcore Design Increases Job Efficiency
Integrating 'unlimited depth' with a universal fastener design allows professionals to consolidate many fastening tools. The HOLLOWCORE™ shaft enables uninterrupted fastening on threaded rods, eliminating a common obstruction. This design, compatible with Square, 12 point, 8 Point, and HEX fasteners, fundamentally shifts how professionals stock their toolboxes.
