The cast-aluminum EZ-Lug Lug Nut Wrench, with its double-socket design, makes a sometimes difficult task quite easy, even for those with limited arm strength. Simply place the tool's main socket over the nut to be loosened/tightened and its adjustable socket over the opposite nut for leverage, then crank. The inner gears do the work. An EZ-Lug kit includes wrench, hand crank, three sockets (sizes 17, 19, 21), and zippered carrying pouch.
