Beschreibung
Zusammenfassung:	A cap system (26C) for enclosing a metallic fastener assembly (11) extending through a structure (14) includes a first securement mechanism (34C) positioned about a periphery of a nut member (22) of the metallic fastener assembly, wherein the first securement mechanism comprises a plurality of grooves (37C) positioned about the periphery of the nut member, and a cap member (28C), wherein the plurality of grooves are spaced apart about the periphery of the nut member, the nut member includes a plurality of ridge members (46C) which extend in a radial direction away from the nut member and define the plurality of grooves, and adjacent ridge members are spaced apart about the nut member. The cap member includes a sidewall (29C) having an inner surface which defines a cavity dimensioned to receive the nut member and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the nut member and an end of the sidewall of the cap member defines an opening which provides the nut member to have access into the cavity.
