Milwaukee Tool HollowCore Magnetic Nut Drivers feature a new thread-thru design, according to the company. They can fasten at an unlimited depth in both threaded rod and long bolt applications, while remaining secure on the application material with a powerful magnetic driver head. The magnetic driver head features a universal design, delivering the ability to not only fit four times more fasteners including square, 12-point, 8-point and hex, but the ability to remove rusted and stripped bolts as well. The drivers also feature wrench-ready hex steel shanks that come forged and chrome plated for maximum durability and additional leverage.
