Abstract
A swage mount that includes a flange, having a first side and a second side, and a cylindrically shaped hub. The hub is primarily comprised of a metal (such as stainless steel), and extends from the second side of the flange, and has an inner surface and an outer surface. The surface of the swage mount is plated with one or more layers of metal, or a combination of metals, which provide a) increased retention torque, and b) increased part cleanliness. This invention may be used in conjunction with surface hardened swage mounts that contain surface protrusions. In this case the metal plating prevents separation of the protrusions from the swage mount, thereby preventing contamination.
