Exhaust

[maxstu]

Yet another agree..................

its a bad state of affairs when we are all looking at this post wishing our nuts were as good as yours

Good to see schoolboy humour again.....
My nuts were so bad that even gentle tapping with a hammer saw them almost disappear

Mine needed a bloody good soak and a bit of yanking but eventually I could spin then between my fingers.

Now I have some nice shiny copper ones.

Thanks for your help!
In terms of replacement nuts and studs where is the best place to go are these two suitable and if there is much difference between the two?

For reasons I can't remember, the general advice I seem to think is not to use stainless exhaust studs.

I bough these a couple of weeks ago https://www.ebay.co.uk/itm/VW-GOLF-MK1- ... 2749.l2649 and they arrived quickly and seemed fine.

Just be aware they come with a 12mm head, not 13mm. Gives you a bit more spanner space, but its not to everyones taste.

Pretty sure that the ones I bought.

Does anyone no the reason/s for not using stainless exhaust studs?

Thanks again for all your help and advice.

Galvanic corrosion, I think. Here’s some reading which will send you off Zzz

Thanks for the info- very detailed!

If you fit stainless studs with threadlock it acts as an insulator and a sealant, preventing the ingress of water and stopping (or massively inhibiting) the electrolytic process. The alternative is mild steel that turns into a rusty stub over a few years.
I prefer stainless studs fitted with a thread sealant, and mild steel or copper coated nuts.
