Abstract
A dual protection inner seal washer employs a radially outward metallic portion having a dielectric coating and a radially inward polymeric portion engaging the metallic portion at an interface with an interference fit. The polymeric portion has at least one tapering compression surface to engage a surface of a structure proximate a hole and further has a fastener element contact surface to engage a mating surface on a fastener system element. Torqueing of the fastener element compresses the at least one compression surface inducing a predetermined pressure in the polymeric portion in a joint created by the fastener element and structure.
