Best Screws or Nails for Attaching Lattice?

Finishing nails work well too and can give a clean look. If you want something a bit different, stainless 9/16 staples can also do the trick, especially if you don't mind seeing a bit more of the fastening process.

I personally just use tiny C-clamps when attaching lattice. It might be a bit unconventional, but it keeps everything secure without worrying about rust.

For attaching lattice, I'd recommend using stainless steel fasteners. They resist rust, which is crucial for outdoor projects. You might also consider hot-dipped galvanized nails or coated fasteners since they're designed to hold up against the elements. 4D or 5D box nails are a solid choice if you want something affordable that will still last long!
