I know Andy got this fixed more than a month ago, but others commented on this so I will too: You can buy Grade 8 SAE and property class 9.8 ISO hardware at an ACE. They actually have a fairly nice selection of quality hardware, at least the one I go to does.

Now, this said, aerospace hardware is in some cases much better suited to double shear applications than that. I'd drop by an FBO at a local airport sometime and see if they have some hardware for you, or check something like:

For a really good layman's text that describes the practical issues with such hardware and has the data you need to compare shear strength, you could check out:

which if you are lucky might be in a local public library.
