Needs to be a stainless hardware option (bolts/nuts, ect.) Or just any bolt that threads into the unibody, suspension parts come to mind.

Stainless nuts & bolts are costlier, and they are weaker so they have to be bigger -- both of which increase their price. Imagine the total savings If Ford reduced the cost of its 15 million F150s by just $10 each. And as the saying goes, "The engineers aren't the ones who have to fix what they design."

But I somehow doubt that Tesla would take cost-saving that far. And it is their employees who have to fix Teslas. Finally, in earlier days the objective was to keep the car together until the 90-day warranty was over, whereas today if 10-year-old rusty nuts snap off rusty bolts, consumers have the power to damage reputation.

Hell yeah. Living by the ocean says all about that. So, there’s no news for me. Actually, I wish I had stayed in Australia. I have a friend who works there at Scrooz. We became friends when he helped me choose the best roofing screws for my house. I spent about 5 years in Australia. I love it so much, but I had to come back to the US because of a better job offer. That was the moment I wished I were a freelancer, but I still love my job. So, guys, let’s keep the topic updated. BW

Grade 8 is what you are asking for and the safest choice for undercarriage. This from Iowan perspective and San Diego coastal resident 30 yrs. Grade 8 is suitable on running gear, suspension and cross members.

Safest meaning imported nuts & bolts are sold in bulk typically inferior in quality, they can contain less carbon which fails quickly: brittle. Grade 8 are stamped atop the head. Ask a clerk to show you how to identify.

S.S. are not equals either. S.S. is not suitable undercarriage. Boat Chandlery, nautical hardware stores such as West Marine are good. Ace Hardware, Do It Centers, Home Depot s.s. hardware have been bulk stainless that works for fencing, latches and equip mounts but not first choice for marine and automotive especially ornamental which is exposed to naked eye.

304 Stainless is also partially ferrous (and magnetic) and will corrode especially in proximity to rusting steel fasteners.

Hopefully, CTs 30X will have more nickel and not rust as easy.

Isn’t all steel partially ferrous? Stainless or otherwise?

Yes, but not all steel exhibits ferrous properties. That comes from there being classifications of properties and element names that overlap from before they knew elements were a thing.

I live by the ocean, so yes.

Don't need to import the salt, the waves throw it in the air.

So you go outside, stick your tongue out, and then take shot of tequila.
