A fastener assembly for attaching components of dissimilar materials includes a fastener having a base portion and a protruding portion, and a mechanism for tightening the assembly. The base portion is shaped to be complementary for mating with an attachment feature formed within the non-metal component such that the base portion is retained within the non-metal component. The protruding portion including a base end and a distal end with the distal end including a threaded portion. The fastener assembly allows attachment of components fabricated from dissimilar materials without forming through holes in one of the components. Additionally, the fastener assembly compensates for differences in thermal expansion rates between the non-metal component and the metal component while providing a tight attachment therebetween.
