May I ask a question, I am more familiar with buildings regulations than cars. There is a corrosion called Galvanaic corrosion https://en.wikipedia.org/wiki/Galvanic_corrosion, caused then two different alloys of metals are put together. All two metals will corrode slightly but the further apart they are on the Galvanaic table the faster the reaction. Carbon/mild steel and then stainless steel are far apart and therefore if they are installed touching they will corrode and corrode fairly quickly. In buildings where used externally you are required to separate these two metals using an electrical insulator to reduce corrosion. In cars, bolts, frame rails, exhausts etc are commonly used touching mild steel. Is it just accepted that corrosion will take place and when it does the part will be fixed later? Vibration from the car will cause capillary action to draw moisture between frame rails and floor pans therefore surely the two should not be used together?
 
If you follow the link above one of the first products you see is anti-seize compound. Perhaps this would slow the disimilar metal corrosion?

That aside, I would much rather have slight thread corrosion than a bolt head thats so rusty it's no longer the same shape!
 
Merry Christmas, hope Santa has been kind to everyone.

Its not the stainless bolt that will corrode, its the mild steel metal that is bolted to that will be sacrificial. Imagine normal corrosion then multiply with with a time factor of 10x for electostatic corrosion. But yes please use anti seize compound which is likely to contain nickel which will act as a sacrificial metal therefore protecting the metal bodywork, and then replace the compound every 2 years or so.

The other option is to avoid the hassle and use mild steel bolts which already have a nickle coating, again this will not least forever as the nickle will dissolve eventually but this is a designed solution.
