The ComfortGrip handles fitted to the hex drivers ensure the maximum torque transfer when loosening stubborn screws, as well as being easy on your hands. The T-handle design offers the choice of a long blade for greater access and speed, or a short side blade for more torque on hard to shift screws. Made from high quality chrome-vanadium-molybdenum steel each of the T-handle hex keys has a one-piece blade to withstand even the highest stresses. The ChromTop® blade tip ensures the highest accuracy at both ends. The set comprises 2.5mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm, 8.0mm.
