Re: I didn't know they made color coded nuts
"Stainless steel studs and nuts the worst material for electrical connections. they seem to come loose easier then bronze or copper "
I'm told the surface of stainless threads is smoother than other metals (including galvanized) and that because of this, it is easier for them to slip and come apart.
Which is why you learn to use threadlock on every threaded fitting, religiously. And to throw out the old bottle and buy a new one every two years, because it does have a shelf life and it does go bad as it ages.
