Maze Hot Dipped Galvanized Ring Shank Lumber Nail Double hot dipped galvanized ring shank nails for the new treated lumber. Made from stiffer stock steel so the shanks can be smaller in diameter to help reduce wood splitting without bending. Ring and spiral shanks provide exceptional holding power. Producers of treated lumber and many building codes specify hot-dip galvanized or stainless steel nails because they have a rust-free life expectancy comparable to that of the treated lumber. Stormguard P.T.L. nails are double dipped in molten zinc.
