Only thing that I can think to do is to thread 2 or more nuts onto the brake boss threads and then tighten them together with high torque. Then grip this pair of nuts with a spanner and try to undo to the brake caliper bolt.
...or grip the brake boss bolt in an axle vice with soft jaws or an inner tube as protection.

Hmm I’ve never been able to get the 2 bolts tightened together technique to work before. I’m going to have to see if I can get access to box aren’t I.
I might have some spare bosses somewhere too so I might have to cut the boss without damaging the brake, but that sounds like a pain in the arse too.

Amazingly I had some bolts that fitted the boss and even more amazingly I managed to got it to work.
Thanks for the help! Very much appreciated

Does anybody have any idea what I can do with this. It’s a v-brake calliper and the brake boss. It would appear that the v-brake bolts are too long for the brake boss as I can’t tighten up the bolt, but I only worked this out after I’d gone too far and now I’m unable to undo the bolt and it just unthreaded itself from the frame.
I don’t have any tools narrow enough to get to the flat part of the brake boss to get a grip on it.
It would be good to save the boss and the calliper if possible?
