Abstract
A resilient washer design having an annulus body and a concentric sleeve extending from the annulus with a plurality of ribs extending from the sleeve. The washer may have an opposing sleeve extending from the opposite side of the annulus with a second plurality of ribs in staggered location to the first set of ribs. This staggered position allows the annulus to flex between the ribs on opposing sides and resist compression of the washer when pressure is applied axially.
