bright vs galvanized common nails

Taylor's picture

Is there any reason not to use galvanized instead of bright common nails? Granted galvies are for wet environments, but even interiors can be pretty moist (lots of rusted-out nails in my house in the vicinity of kitchen and bathroom). Galvanized nails would not have the (small) galvanic reaction you'd expect with common nails and HDG joist hangers e.g. Simpson's zmax which is all Homer carries. And anyway that galvanized stuff doesn't seem much use in the new PT lumber....

I can only think that withdrawal resistance might be less because of poor galvanization flaking off, but that seems like a bit of a stretch....

I would think the galvanized should have better pullout, as the rough texture would help the wood grip better.

The main disadvantage of galvanized is that they generally (being rougher) require more force on insertion and hence may cause splitting or other damage.

I carry around a bucket containing four parachute bags of screws and nails, so that I'm never wanting for the right fastener. To keep inventory down I have mostly galvanized nails and screws. For hanger nails I have some of the Simpson "special nails" that are basically intended for decks.
