These are custom chrome plated 316 stainless sheet metal screws with tin-cobalt RoHS compliant chrome plate finish, with the 316 stainless steel designated by a dot on the head of each screw. Like the other custom tin cobalt chrome plated screws, these type A 12-11 X 1-1/4 phil pan sheet metal screws 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.
