Fastener eliminates thermal stresses and maintains snug fit. Conicalhead bolt and metal washer main components of fastener that keeps constant tension on carbon/carbon parts regardless of thermal stress. Fastener used in cases where fastened parts have unmatched thermalexpansion coefficients. Does not become looser or tighter as conventional bolts and nuts or rivets do at elevated temperatures.
