These unique hex keys are made of chrome-vanadium steel, through hardened and chrome-plated. They have a reduction in the length of their short ends and a 95° rather than 90° bend. These two features make them especially useful for gaining access to hard-to-reach screws and working in confined spaces. Thanks to the 95° bend, the increase in the hand working space can reduce the risk of injury to your knuckles and fingertips. The ball end enables the user to work at angles up to 25°. The ProStar holder allows the easy removal of each key without moving any others. Nine keys, size range: 1.5mm to 10mm.
