The Milwaukee 48-22-2421 Hollow Shank Nut Driver (1/4") is a compact, versatile tool designed for precision fastening and deep reach applications, making it ideal for smaller fasteners that still demand durability and control. With a 3" hollow shaft, it easily handles long bolts and threaded rod, while the universal driver head adapts to multiple fastener types—saving you from constantly swapping tools. Add in a wrench-ready hex shank for extra leverage, and it’s ready when those “easy” fasteners decide not to cooperate.
