Fixing shiplap cladding to shed

I'm building myself a shed to fit down the side of my house due to it being an odd size and shape and now ready to clad the outside.

Can anyone suggest the best fixings for securing the cladding?

Was looking at oval nails but only seem to be able to find bright oval nails in the length I need (30mm) and worried that they'll rust.
Any advice welcome on alternative fixings.

each board expands and contracts as the weather changes (across its width but not along its length) so you can fasten each board with one screw to each batten it crosses, and let the board above hold its top edge. Drilling the boards will reduce their tendency to split at the nail or screw. If you use two or more screws through a board on a single batten, it will split in summer.

I used countersunk brass screws, for a small section on show. If you are near the sea you will need brass or stainless; elsewhere, bzp will last a few years before it rusts. Nails are cheaper.

You can put tilers' felt, and insulation, behind the boards. They are mostly to shed the rain and look pretty. I treated mine with fencestain on all surfaces before assembly. It is impractical to treat the top and bottom edges afterwards, never mind the backs. They add a bit of stiffness but are not structural, so you don't need huge fixings.

BTW the two boards neatest the ground will rot quickest due to damp and rainsplash, even if they are on a dwarf wall. Fix them with screws so you can remove and replace. Make the replacement boards while you are building, and tuck them away as spares. Treat the bottom two boards with wood preserver, not just stain.

Thanks for the reply and some good tips.
Feeling inclined to go with nails but not necessarily clout nails as would prefer not to see the heads.
Was thinking of something like these

Galvanised ring shanks are the norm.

deleted - got wrong end of the stick. ha ha ha

Correct me if I'm wrong, but aren't galvy nails notorious for working loose over time?
Just something (I think), I recall hearing.

Never heard of that but certainly not the case with ring shanks?? That's the whole reason they are ringed?

Might have been clout nails then. Or it could be me dementia.
