Nine hex keys that you will never have to fiddle to extract from the holder.
Rotating a single key means all the other keys rotate to the side, making all the keys ready for removal.
A simple single turn makes getting hold of the right key easy.
The keys themselves are chrome-vanadium steel, through hardened and chrome plated.
The ball end allows the key to operate at up to 30° from the vertical, very useful in awkward corners.
The nine piece set is a delight to use and covers the size range from 1.5mm to 10mm.
