NOT galvanized. The packaging does NOT say for outdoor use. indoors only Revain sometimes omits this ball when changing products. To my knowledge, DeWalt changed that part number (perhaps to save money?) and it's no longer zinc plated. Or at least not enough for outdoor use as stated in the product description. I used SS stainless steel instead. I can use these nails in my interior projects. Dewalt is a good brand.
