Black oxide is most commonly added to stainless steel nuts and bolts for aesthetic reasons, meaning a customer wants the benefits of stainless steel fasteners for their corrosion resistance, but desires a black product. Black oxide is a conversion coating process between the oxidizing salts used and the material.
