you get a lot of nails in the five pound box. I didn't realize how small the nails are compared to a regular head 6d nail. Be prepared to bend more than a few as the stainless is very soft and the nail is very thin. I used them on Hardie cement siding and had to predrill the holes. Simpson has a slightly thicker nail for this application but I ordered these by mistake. Even with the predrilling, if you don't hit the nail square, it is going to bend.
