A structure has a pair of components, releasably secured to one another by fasteners. The fasteners include a plurality of studs secured to one of the components and passing through holes in another of the components with a spacing between the radially inner surface of said hole and a radially outer surface of said stud to define an annular void between each hole and a respective one of said studs. The fastener also includes a nut having a blind bore extending from an end face and threaded to receive said stud. A seal assembly provides a seal between said components. The seal assembly comprises a first resilient seal extending between and located on the studs to be interposed between the components and a non conductive bushing on each of the studs and located in respective ones of the annular voids. Each of the bushings has a radial flange to overlie the periphery of said hole with a pair of resilient gaskets located on opposite sides of each of said radial flanges. A rigid washer is located on a respective one of the studs and overlying one of said first resilient gaskets. A second resilient gasket is located on the opposite side of the washer to the first resilient gasket to sandwich the washer between one of the first resilient gaskets and the second resilient gasket. An 0 ring located on the stud between an end face of the nut and the second resilient gasket to effect a seal therebetween. Upon tightening of the nut on the stud, the gaskets are compressed to provide a seal between adjacent surfaces and the bushing maintains the stud spaced from the holes.
