These are cheap nails and work as advertised. Definitely not intended for anything more than drywall. They bend very easily. I've used them to hang garlands on my patio and the outside wall is pretty solid. I bent quite hard and couldn't get them all the way in. I ended up brushing my thumb a bit as one of them bent and bounced off the hammer. All in all, these are good nails. They should be easy to use. Nothing remotely heavy.
