additional information:product dimensions:231 x 35 x 73 mm (l x w x d)l-key set in ergostar holderhexagon with ball end magicring 9-piece matt chromein many l-key holders removing and reinserting individual keys into the holder is cumbersome. The wiha ergostar holder is the ultimate and ingenious solution to this problem. Turning one l-key in the holder causes all the other keys to rotate sideways at the same angle allowing quick and convenient removal. the fastening system used in these holders prevents keys from falling out regardless of whether the holder is closed or open. the use of a magicring (from size 3) made of spring steel prevents standard hexagon socket screws from falling out of the key regardless of position without the need for a magnet. the hexagonal shank with a ball head allows for trouble-free tightening at an angle of up to 25°. The key wrench set contains nine hexagonal keys in popular sizes and can be hung directly at the workstation using the eyelets on the holder. Matte chrome-vanadium steel ensures durability and solidity. applicationsuitable for tightening or loosening hexagonal head screws in hard-to-reach places and removing recessed standard screws inserting and screwing in horizontal oblique or deep blind holes.the set includes:- allen key 1.5 mm with ball head and magic ring- allen key 2.0 mm with ball head and magic ring- allen key 2.5 mm with ball head and magic ring- allen key 3.0 mm with ball head and magic ring- allen key 4.0 mm with ball head and magic ring- allen key 5.0 mm with ball head and magic ring- allen key 6.0 mm with ball head and magic ring- 8.0 mm allen key with ball head and magic ring- 10 mm allen key with ball head and magic ring**
