Abstract
A cap system for enclosing a metallic bolt fastener extending through a structure which includes a first securement mechanism positioned about a periphery of a bolt head of the metallic bolt fastener. The cap system further includes a cap member which includes a sidewall having an inner surface which defines a cavity dimensioned to receive the bolt head and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the bolt head. The cap system further includes an end of the sidewall of the cap member which defines an opening which provides the bolt head access into the cavity.
Claims20
A cap system for enclosing a metallic bolt fastener extending through a structure, comprising:
- a first securement mechanism positioned about a periphery of a bolt head of the metallic bolt fastener, which comprises threads which are interrupted and are defined by a plurality of ridge members positioned on the bolt head;
- and
- a cap member comprising a sidewall, having:
- an inner surface which defines a cavity dimensioned to receive the bolt head and defines a second securement mechanism complementary configured to engage the first securement mechanism positioned about the periphery of the bolt head;
- and
- an end of the sidewall of the cap member which defines an opening which provides the bolt head access into the cavity.
A cap system for enclosing a metallic bolt fastener extending through a structure, comprising:
- a first securement mechanism positioned about a periphery of a bolt head of the metallic bolt fastener which comprises continuous threads which extend about the periphery of the bolt head;
- and
- a cap member comprising a sidewall, having:
- an inner surface which defines a cavity dimensioned to receive the bolt head and defines a second securement mechanism which comprises continuous threads complementary configured to engage the continuous threads of the first securement mechanism;
- and
- an end of the sidewall of the cap member defines an opening which provides the bolt head access into the cavity and defines a groove which extends about the cap member;
- a first opening defined by and extends through a first portion of the sidewall of the cap member wherein the first opening communicates with the groove such that a first flow path extends through the first opening and into the groove for conveyance of a sealant;
- and
- a second opening defined by and extends through the first portion of the sidewall of the cap member with the second opening spaced apart about the cap member from the first opening and the second opening communicates with the groove such that a second flow path extends from the groove through the second opening of the cap member for conveyance of sealant.
A cap system for enclosing a metallic bolt fastener extending through a structure, comprising:
- a first securement mechanism positioned about the periphery of a bolt head of the metallic bolt fastener comprises a plurality of grooves positioned spaced apart about the periphery of the bolt head;
- and
- a cap member comprising a sidewall, having:
- an inner surface which defines a cavity dimensioned to receive the bolt head, and defines a second securement mechanism which comprises at least one annular ledge positioned along the inner surface of the cap member;
- and
- an end of the sidewall of the cap member defines an opening which provides the bolt head access to the cavity.
