Running out of manifold exhaust copper nuts. Before looking at getting new stock I would like to know what is best for heat, copper or bras, maybe something else. We all know that old exhaust copper nuts are slowly burning away and can be a pain in the arse to remove.

What is this stud made off, seems to be harder or coping better with the heat

Viking,
the 'copper' nuts which I've used in the past seemed to be copper plated, whereas the brass nuts now available are solid, so a much better bet.

Exhaust manifold studs are likely to be high tensile steel, perhaps 10.9 grade...

ken.

Thanks Ken. I somehow knew the answer. Will find some bras nuts.
Cheers

Viking bastard
