Don't put a stainless nut on a stainless stud.  They will gall.  Better to go with one stainless and one regular steel.

ACE, seen the brass nut comment a couple of times, why brass?
Because the brass nuts won't rust on to the studs, and they always come off nicely when you need to take them off.

We started using brass nuts at the British car shop where I worked in 1973, because we were always fighting with rusted and seized exhaust hardware which also often caused broken studs in the heads and exhaust manifolds. On all our exhaust jobs, we began using brass nuts, and when these cars came back in for some job that required exhaust removal again, the nuts came right off. No need for soaking in penetrating oil, or heating them up with a torch, or busting them off.
They worked out great.

BTW, the guy who owned that shop rode a RE Interceptor 750.

Got a source for those brass nuts? I have had them on British cars too. I thought they came that way.

The brass nuts (which I always thought was a venereal disease) are a trick that go back to at least the 1950's when I was a kid and probably before. It was standard operation practice and many cars came that way from the factory. They are a GREAT idea. Also some people think it is a good idea to use a spot of oil on them to get a true torque reading or get them over rusted threads. NEVER do that. The oil or grease only carbonize with the heat and make things worse. Use a Graphite based anti-seize - normally messy as hell).
Always remove them with a 5 point socket to avoid rounding the corners.

A good hardwate supply should have them. I don't know the size you need, but you could cjeck Fastenal or McMaster-Carr.

I've noticed lots of exhaust nuts I've seen over the years are brass or copper coated.  As they don't usually need to be torqued very tight, solid brass should do fine.

I heard when he saw that word, "Czech" he said, "HELL YES!  I want it to CHECK!!",  so he poked that button.  :o

I had to disable my autocorrect on my phone, because it was driving me crazy with  word substitutions that were wacky.
So now, when I use my phone, I have no spell check, and sometimes I fat finger the little keyboard on the screen.

My former boss sent an e-mail to the President of our company division. The Pres's last name is Motzkin.
He used the Spell Czecher and it changed it to "Goat Skin", and he received an immediate reply.  ::)
