Abstract
A high temperature gasket assembly comprises a plurality of identical symmetrically shaped plates with holes offset from a centerline of each plate. The plates are rotated or flipped into an orientation with the outer periphery of each plate in alignment and the holes in a first plate are skewed with respect to mating holes in a second plate. As a result, a portion of an inner periphery of each hole is in facing relation with an inner face of the other plate. The resulting aperture defines an interference orientation with a diameter greater than a minor thread diameter and less than a major thread diameter of a mating fastener. Thus, the fastener is retained within the aperture without undesirable separation.
