yup, Fastenal. Used to get some from Airparts, Inc. in Kansas City along with Kle-Co (sp?) clamps, drill bits, mill cutters, etc. They sell stuff that's been "de-commissioned" from areospace/aeronautical businesses but is still otherwise useable for us "low-tech" guys. Also sold scraps, cutoffs, and misc. really cool stuff like aeronautical guages, etc. Once even made a sweet table with some landing gear parts we got from them. I've been gone from KC for a few years now, but I think they're still in business & do have a catalog.
