I got a 5/16", grade-8 machine nut and filed the hole out to a 7mm square opening. (The 5/16 threaded hole is just about the perfect starting point to enlarge the hole to a 7mm square shape.) I can now place the modified nut over the square head of the adjusting bolt, and can turn the nut - and bolt - using a 1/2" box-end wrench. (5/16 bolt has a 1/2" hex.) Works great! I'll probably "J-B weld" the nut into a 1/2 box-end wrench, creating a complete, dedicated rear-brake adjusting wrench.
BTW, it's like night and day the difference in the amount of grip the square box-end opening has compared with a little 7mm open-end wrench.

And the square part is set back from the front of the socket, so you'd have to grind it as well. You would probably have to modify (destroy) a tee handle tap driver by grinding the fixed handle off to fit... Perhaps it's time to take Johns advice and free the thing up.

(I do wonder whether I can get one that will work in the confined space between the rear brake backing plate flange and the lower connection point for the shock, though. Kinda tight in that area.) I actually have one style of adjustable tap driver myself. I'll have to see if I can make it work. If you think you have something at work that might do the trick, I'd be interested in finding out what it is.
