I posted this in another forum and decided to give it's own string where it could do the most good
www.mcmastercarr.com has just about any kind of hardware you could want (3577 pages) and they deliver quick. Very quick in most cases I get stuff overnight via fedex. I just did a search for elevator bolts folks were looking for and they carry them. They also carry a lot of equipment and shop stuff too.
Good luck on your project!
Jim
