Is the type of nail important for the type of job? Yes, pressure treated fence boards require the use of outdoor rated galvanized nails. You can see the rust lines in the fence picture attached. Using quality supplies make your fence stand out.

An iron nail in wet conditions will have rusted before you have a chance to pay the invoice on your new fence investment. Rust isn’t just unsightly, it’s a weakness that will decrease the life of your fence or deck. Galvanized nails are dipped into molten zinc. When the nail is removed from the zinc, a chemical reaction takes place, forming a crystalline pattern called spangle. This coating is designed to protect the metal inside from rust and corrosion, extending the life of the nail.

The other important factor to consider is using ring shank nails for your fence build.  These specially designed nails have a textured edge that helps them firmly grip into wood, making them great for nailing on floors, walls and other lumber that needs to withstand movement and wind forces. Ring shank nails provide a 288% greater pull-out resistance than smooth shank nails, meaning your project will stay secure over time.

Standard steel nails will rust and corrode from exposure to moisture, from both the exterior elements and the chemicals in pressure-treated lumber. Galvanization is the process of coating the metal with a layer of zinc, which helps protect the nail from corrosion and improves its durability. This process allows galvanized nails to withstand exposure to moisture and other elements that could cause rust or structural failure.

The use of quality supplies such as Galvanized nails are recommended for use in pressure-treated wood, making this combination the most cost-effective fencing option. So if you’re planning on building a fence with treated or exterior wood, consider using galvanized ring shank nails.
