Wiha 66988 ErgoStar Ball End Hex L-Key Set, 13-piece Inch
This inch set runs from .050 up to 3/8 in thirteen steps, so it includes the larger 1/4, 5/16 and 3/8 keys that small sets leave out. The ErgoStar holder fans all keys open with one movement and clamps them so they do not fall out, which helps anyone with limited finger dexterity. The keys are chrome-vanadium-molybdenum tool steel hardened to 60 HRC, with chamfered, CNC-machined tips and a satin finish.
