Depending on how tight the bolt is in there because you have a bit sticking out you can afford to mess about with "cutting a slot" for a flat bladed screwdriver. On the whole because the shank of the bolt isn't hardened this doesn't always work - but you know with a bit of scraping around the threads where they go into the box section (which is where the corrosion is most likely to have taken hold) you might get lucky.
