Abstract
A spark prevention cap is disclosed. The cap forms a sealed cavity around an end of a fastener protruding from a surface of a structure, for example, an aircraft structure. The cap has a cap body with an annular base terminating at a rim. The rim surrounds an opening into a central cavity for receiving the end of the fastener. The annular base has an external circumferential surface extending from the base rim, and a mating feature on the external circumferential surface configured to contact a sealant material applied externally to the cap.
