Black Oxide Screws, Bolts, Nuts and Washers in Stainless Steel

Looking for Black Stainless Steel Hardware? Black Oxide Fasteners made from stainless steel, (usually grades 18-8 or 304) have been chemically treated to alter certain qualities of the material, most notably the color. The treatment also adds a mild corrosion and abrasion resistance (in addition to the plain stainless steelís nature), and reduces the now black oxide stainless steel fastenerís reflective properties. To achieve maximum corrosion and abrasion resistance, the black oxide may be wax coated or oiled. Wax coated product is more dull, where as oil sealed product is spun off to remove excess oil and may be bright or shiny. Wax coating complies with military specifications as a Class 4 finish. Black residue may come off of these fasteners, so they should be wiped down before being applied in applications such as jewelry or finishes where they may come in contact with hands.


Black stainless steel hardware that has been treated in this manner is commonly used in the automotive industry on both car and motorcycle builds. Black Oxide Screws , Bolts and Nuts are also commonly used on dirt-bikes, 4 x 4's, ATV's and other off road vehicles, as well as in racking systems for automobiles including roof racks, grills and luggage or general gear racks. Additionally, this type of stainless fastener finish is often used in gun and knife builds, particularly in the handles, because of its corrosion and abrasion resistant qualities. Of course, black oxide fasteners are also used for their sleek black look as well.
