Finally, the perfect Allen Set! Applied has done it again with this Allen Set. With a ergonomic L handle with a short hex on one end and a longer ball point hex on the other end you will be able to screw and unscrew any hex bolt. Each wrench size is visibly marked on each handle and the whole set comes in a custom carry case with a window. Sizes include: 2, 2.5, 3, 4, 5, 6, 8, 10, and 12 mm.
