Abstract

A novel fastener assembly is disclosed for use in securing a frame section to a composite panel or the like, said fastener assembly being dielectrically insulated from said frame section to prevent galvanic action. The fastener assembly is comprised of a bolt member adapted for engagement in a bore formed in said frame section, said bolt member having an enlarged head portion including annular axially facing groove means, and an annular axially extending non-conductive elastomeric gasket member disposed in said groove means, and a nut member having an enlarged head portion for engagement with said bolt member. The nut member is disposed in a coaxial bore formed in said composite panel and engaged with said bolt member also disposed in said bore. Upon assembly the gasket member is clamped between the frame and the enlarged head on the bolt and is deformed axially and radially. That is, the gasket is extroded into the spore between the bolt member and the frame to insulate said bolt member from said frame section. In addition, the aforementioned gasket member provides a watertight joint when said bolt and nut members are brought into clamping engagement with said frame and panel sect…
