I have sets of allen keys and they are too small and too big
Where I live there is no decent LHS that has anything, and no hardware stores keep hex drivers suitable, so I need to order one from Tower or somewhere, hence the fact that i need to know what size to order.
I want to get a nice driver but dont know what size, im not playing hex driver roulette and hoping i order one the right size! not at the prices they charge for the things!
