Sealable fastener with circumferential sealant channel and sealant delivery passageway for delivering sealant into the circumferential sealant channel

A sealable fastener for insertion into a fastener opening in a receiving structure, the sealable fastener comprising:

• a fastener shank comprising a shank first end having a fastener head and a shank first end wall, and a shank second end having a shank second end wall, a shank side wall between said shank first end and said shank second end and having a fastener thread and a circumferential channel in said shank side wall extending to said fastener head;
• a sealant delivery passageway having a delivery passageway entry port in said shank second end and extending to a delivery passageway exit port opening into said circumferential channel;
• such that a flowable sealant placed in the fastener opening is drivable into said delivery passageway entry port as the fastener shank is inserted into the fastener opening, and such that the sealant flows through said sealant delivery passageway and exits through said delivery passageway exit port and flows into and around said circumferential channel, creating a circumferential seal between said fastener shank and the fastener opening in the receiving structure.
