Not to belabor this, but are you adjusting the cones with the wheel on the bike? If so, please see my previous post. If there is an advantage to doing it with the wheel installed, I'm afraid I don't see it. My lock nuts are also narrow (about 4mm), but it doesn't prevent the use of a thicker wrench.
