Are there any downsides to using stainless steel fasteners in place of the regular fasteners for timing covers, oil pan, accessory mounts, water pumps, etc?

Thanks!

Of equivalent grade, absolutely not. Stainless hardware is far superior in that they will not rust like plated steel will

 

Thanks!

 

Use anti seize.

 

Your wallet will feel the difference

 

That was a quick post.
I use Stainless Steel bolts quite often at work.
They are a pain. Grab a 3/8 bolt and nut, tighten them down with an air ratchet. Good luck getting them apart.
That goes for all Stainless nuts and bolts.
Most, and I mean 90%, need to be cut off.
I've found antiseize helps.
We use Stainless when bolting aluminum pieces together.
Other than that I avoid them.
I will use Stainless washers with a standard bolt on aluminum if they're sight unseen.
