This applies to the 300 grade of ss the 302 303 304 304L 316 316L And so on, now this ss can get a stain on it but it is not easy to do . these grades are used for knifes, medical things, jewelry and much more. these also give you the best shine.
The 18/0 is the 400 grade 416 440a 440b 440c And so forth they will rust some because they do not have the nickel in them they are also much stronger than the 300 grade. the 400 grade is also magnetic, so the myth that ss isn't magnetic is just that a myth.
17-4 ph is one of the strongest ss used on aircraft, lots of military things.
there are over 150 grades of ss but we only use about 30 of them.

Here is a place you might want to look at. I do not have a sales pitch about them, other then I have used them and the service was good.

I have, like Vince (302 Z28) purchased hundreds of dollars worth of stainless fasteners from McMaster-Carr and have yet to see any rust on any of them. More have come from Stainless Specialties and a guy I see at swap meets here in the NY/MA/CT/VT area. Never a bit of rust on the 300 series SS tho some that are 17-4, I believe (from elsewhere) do show some discoloration, but no rust. My guess is that what are on that car are what came with the molding (especially if it's replacement aftermarket) and are probably chromed carbon steel.
Here's a good chart to start with, drill down if you need more:

|redsdad||Rub 304 or 316 with a piece of carbon steel or use tools such as a file which has been used previously on carbon steel and then see what happens. It will rust.|

And if you don't yet have enough choices, I have had success with Bob's Stainless Fasteners.
I think he is a one man show, has some nice unique products.
BTW, stainless ought not have rusted, perhaps those screws were chromed steel?

All the stainless fasteners I have received from McMaster Carr have been either US or Taiwan manufacture marked on the box. While building my 34 I probably ordered $400 worth of stainless fasteners from McMaster Carr. That was several years ago however.

I use Fastenall. They can get just about anything when it comes to a fastener.

Although I use McMaster for some of my fasteners and for most of my other raw materials, I use Totally Stainless for all of my stainless fasteners. They even sell the ARP line of stainless high strength bolts.
Every invoice I get from Totally Stainless shows the country or origin for each product. Some are US, most are import. If you are in doubt about the quality of your fasteners, call them before you order and they will tell you where the fasteners come from.

Hate to tell you guys, but lots of those SS fasteners from Mcmaster are imported.
- How do I know:- Canada had an anti-dumping
tariff on Chinese SS and Mcmaster refused to send them north to me a few times.

I've bought lots of fasteners from the Bolt Depot; all of them
very good quality. I assume they're USA made.
They carry all types, sizes, materials, grades, etc.

Yep McMaster Carr
