Abstract
Radio noise in an automotive vehicle is suppressed by grounding the hood of the automotive vehicle with a conductive washer. The conductive washer is concave and is disposed around a rivet used to pivot a hood hinge component to a body hinge component. When the rivet is set, the hinge components compress the washer so as to permanently load the washer to thereby ensure continuous grounding of the hood to the body. Preferably, the rivet is coated with a dry lubricant, such as TEFLON.RTM., which does not flow away from the rivet to interfere with electrical contact between the washer and hinge components.
