This 10mm hex bolt is on a 1995 Lexus so I'd imagine it's been there for many years. I've sprayed it with penetrating fluid and I'm wondering what else to try. More time for the fluid to work? It's only been an hour? And what after that if that doesn't seem to work?
Obviously, the last thing I want to do is round it out.
