Varies from maker to maker.

If you're screwing a malleable iron fitting on a steel pipe you will

Pipe wrenches are used for threaded galvanised pipes. These are still
used in many areas. I've just installed an outside water supply which

lucky that most compression nuts are a fairly standard size (note I said
'fairly', not consistently), so the centre hex portion of a joint is
whatever the maker wants it to be.
