In a perfect world you might be right but in practice it aint so. Have many times seen it gall on everything from high tensile steel to high sulphur free machining steel esp if out in the elements.Quote:

I've only had that happen with one non-stainless bolt. It was a chromed mild-steel bolt and chromed mild steel nut. I have never had it happen with mixed stainless and high tensile (cap screws etc) or stainless and zp steel.
Your a lucky man
Am sure any fitter with meat works or food industry experience will have come across it ;-) just as i did.
Which is funny, because I'm an engineer who has done a lot of work in meat-works automation and continue to for the food industry. Last year using a lick of food grade grease as lube I don't think I bound any stainless bolts. The year before was a battle, we were trying not to use any lube to appease the clients.Quote:

So you've never actually fitted stainless to steel?Quote:

On regular use threads I wouldn't dare, stainless on stainless, bind.....alot, on steel the hardness of the stainless will chop out the threads when wound on and off at regular intervals, maybe with cautious use of the correct never sieze it would be ok, but I wouldn't
Do you need wheel nuts Rijidij? I have tubs of them
That's part of office engineering, its ok in theoryQuote:

Dougal, you do know your stuff, But I to have had stainless nuts bind on steel all thread and bolts. It is my habit now to througherly clean the thread and use inox spray and be slow and carefull....in the end it is quicker than a binding nut/thread.
I don't care about what the books say, I can show you tonnes of Stainless adjusters which have bound them selves to steel adjusting rods.Quote:

Just do what I have always done and slap a bit of never sieze on the thread and do them up well tight.
I have not had one come loose nore had siezed wheel nuts.
Just put it on the thread not the tapered seat so it's got something to lock onto.

Eh? Read it all again, I've done it many times.Quote:

yep me, should I? (tech answer please)Quote:
