WS2 coating finish
UC RediVac® WS2 coated screw

WS2 Coated (-W/-NW)

UC Components, Inc. offers WS2 coating for all our RediVac® screws, washers, and hex nuts. WS2 (tungsten disulfide) coating provides vacuum compatible lubrication and improved wear resistance for treated components. Our WS2 coatings are applied without chemical binders and are impinged into the product’s surface to ensure dimensional integrity and minimize screw galling, flaking, chipping, and peeling.

Although every plating and coating option that we offer is fully vacuum compatible, the ideal finish for your specific high vacuum application is best defined by your process engineer.
