We supply our customer base a diverse array of custom chrome, nickel, and zinc plated parts in both barrel and more expensive individual racked forms. For those that require better corrosion resistance in the presence of chemicals in a RoHS compliant finish we provide custom tin cobalt chrome plated screws that are made using type 316 stainless steel, designated by a dot on the head of each screw. The parts pictured here are 8-19 X 1-1/4 hi lo thread forming screws. They are manufactured overseas and supplied to our long time customer on a revolving blanket purchase order basis. The tin cobalt chrome plating is done in a barrel plate format for improved cost efficiency, while still producing a very attractive cosmetic finish. Tin cobalt finish typically provides a slightly duller chrome finish than the traditional hexavalent chromium plating. All the custom tin cobalt plated parts we supply are electroplated with a bright nickel under-plate for improved longevity and appearance.
