I've used AAA for the past couple of years since I got my 40, and if they didn't used to carry JIS they certainly do now. That's where I sourced my Allen head air rail plugs. Awesome. You just gotta tell 'em you're looking for JIS, they have stainless too, at least in common smaller sizes that I've needed. Somewhat unfortunately they're only located in downtown Denver whereas Fastenal is all over the place.
