Depending on the type of stress the wood is being treated with will to some extent determine the type of fasteners that can be used. Never use plain or glossy finished nails. Never use slate screws or steel screws without any plating or coating. For most applications, whether using hot-dip galvanized nails and bolts, or for screws, it is recommended to use nails and bolts with a protective coating designed for use with pressure-treated wood.
Knowing the best nails for pressure-treated wood, based on the type of stress the wood is under, will help your project last. Using the correct fasteners in pressure-treated lumber is crucial if you want your screws or nails to hold and not be attacked by the harsh chemicals inside. The first rule is: Never use plain or glossy finished nails. These types of nails do not have any protective coating. You also never want to use slate screws or steel screws without any plating or coating.
Stainless steel is almost always a safe bet, but stainless steel fasteners are often soft (and therefore easy to strip), and they're some of the most expensive fasteners on the market. However, for most applications, the best nails for pressure-treated lumber are hot-dip galvanized nails and bolts. For screws, we recommend screws with a protective coating designed for use with pressure-treated wood. An example is Outlaw fasteners.
Always verify the type of pressure-treated lumber you buy (there are several different types depending on your country) and verify that the fasteners you choose are compatible. Fastener packaging should list suggested use.
