Sockets, Extensions, BitsAs part of a long term environmental initiative, Rhino has partnered with Momento to supply sockets, extensions, bits and other accessories to our environmentally conscious customers throughout North America. Momento exclusively developed a coating without using any heavy metals in the surface treatment process. This new coating, Momento Silverline™, has been developed with the aim to protect the environment through an environmentally friendly manufacturing process, but also to help clients worldwide respond to new environmental targets. Until today, black oxide has been the most common coating used on impact sockets because paint or chromium is not approved by ISO standards. Years of research and testing has proved that Momento Silverline™, with its light silver hue meets or exceeds all the performance characteristics of previous products.
