Abstract
A washer for use with a fastener to join two components or plates includes a washer body having an inner portion and an outer portion joined by a connecting wall. The inner portion and the connecting wall form a cavity and the outer portion extends outwardly from the connecting wall to form a flange. The washer joins two plates fabricated from dissimilar material and minimizes stress in the joint. Additionally, the washer minimizes leakage through the joint and can be used with standard fasteners.
