If you can get good quality zinc plated yes but screws vary immensely
in the quality of the plating and in the steel. Brass or stainless
might be a better choice. I don't use anything but brass, stainless or
hot dipped clouts outside up here. Steel screws or nails just doen't
last.

What about galvanised nails, for nailing the boards (galvanised ovals if
there is such a thing)?

Was any of the wood pressure-treated? I'm not sure that you can use
galvanised with that (I always thought they were OK, but then saw a
warning on a box the other day that they weren't suitable for PT lumber).

With plain old fixings, the stuff they use for the treating reacts with
the metal and they corrode quickly.

I'm not sure if the same is true of brush-on preservatives, or if it only
applies to pressure-treating.
