The invention provides a method of manufacturing a metallic-composite joint comprising a metallic component having one hole in a surface thereof, and a metallic fastener having a head portion for attaching to the metallic component and a tail portion for attaching to a composite component, comprising the steps of positioning the metallic fastener such that the head portion of the metallic fastener is retained in the hole, and the tail portion of the metallic fastener extends out of the hole, arranging layered fibers of an uncured composite component on the surface of the metallic component such that the tail portion extends through a gap between adjacent fibers in each fiber layer, and curing the composite component. The invention also provides a metallic-composite joint, a structure, an aircraft structure, an aircraft, a method of manufacturing a fastener assembly, a fastener assembly and a metallic fastener.
