Corrosion Problems
Tannic acid in oak lumber corrodes iron and steel. Oxides leached from rusting metal bleed away from nails and screws, leaving dark stains. Either brass or plated steel screws resist corrosion and don't leave metal stains in oak. Because brass shears easier than steel, working with brass screws in oak requires larger screw diameters. Plated steel screws offer more strength than brass, but for the strongest hardware and best corrosion resistance choose stainless steel screws. Marine quality stainless steel wood screws resist saltwater and chlorides as well as the acids naturally contained in oak.
