What kind of nails should I use for pressure treated wood?

The manufacturers of ACQ, CA, ACZA and CCA and the treated wood industry are all recommending hot-dipped galvanized nails and stainless steel nails and screws with their treated wood products. Furthermore, they specify that the fasteners meet the ASTM A-153 specification for hot-dipped galvanizing.Click to see full answer. Beside this, do I need special nails for pressure treated wood?The first rule is: Never use common or bright finished nails. For most applications, however, best nails for pressure treated lumber are either hot dipped galvanized nails and bolts. For screws we recommend using ones that have a protective coating that is designed for use with pressure treated lumber.Secondly, can you use zinc coated screws in pressure treated wood? We do not recommend electro-galvanized screws (also called clear-zinc coated) for exterior applications. They will corrode quickly in contact with the elements. Mechanically galvanized screws are generally suitable for decks and other outdoor projects made of pressure-treated lumber. Subsequently, question is, can you use aluminum nails in pressure treated wood? Nail manufacturers recommend that you go with aluminum or stainless steel fasteners when you’re using either of these woods—and whenever you’re using pressure-treated wood. (The preservatives incorporate salts that react with the zinc.) Also, never use galvanized nails with copper flashing.Will pressure treated wood corrode metal?In Contact with Treated Wood. The change in chemical formulations increased the corrosivity of the wood when in contact with metal parts. The two most popular chemicals for wood pressure treatment are alkaline copper quaternary (ACQ) and copper azole (CA), which are both active corrosion materials.
