MAZE STORMGUARD T447S530 Deck Nail, Hand Drive, 8D, 2-1/2 in L, Steel, Galvanized, Spiral Shank
These nails are made from stiffer stock steel so the shanks can be smaller in diameter to help reduce wood splitting without bending. Spiral shanks provide exceptional holding power. Producers of treated lumber and many building codes specify hot-dipped galvanized or stainless steel nails because they have a rust-free life expectancy comparable to that of the treated lumber. Nails are double-dipped in molten zinc.
