Review on 🔩 PORTER CABLE PNS18125 1/4 Inch Narrow Fasteners - 1000 Pack by Ronny Welch

It says they are zinc plated. I couldn't find any confirmation of this on the packaging. Also, I was annoyed that I saw the words "Not for outdoor use" on the packaging halfway through my project. My understanding is that galvanized metals are suitable for outdoor use. It would be helpful if use/application were more clearly stated on the packaging and listing.
