Bonding Fastener with Environmental Seals
First Claim
1. An electrically conducting fastener comprising:
- a) a first component comprising a shank having two ends, with a head at one end, said head having an inner perimeter around the shank, an outer perimeter, and a facing surface with a plurality of teeth extending axially between the inner perimeter and outer perimeter;
an inner resilient seal on the facing surface of the head, located radially inward of the teeth and an outer resilient seal on the facing of the body, located between the teeth and the outer perimeter of the head; and
b) a second component comprising a metallic body, a central bore mating with the shank of the first component, and a surface having an inner perimeter around the central bore, an outer perimeter, and a plurality of teeth extending axially between the inner perimeter and outer perimeter;
an outer resilient seal on the surface of the body, located between the teeth and the outer perimeter of the flange and a resilient thread seal in the inner perimeter for sealing around the shank of the first component.

Abstract
A bonding fastener having two components which electrically bonds metallic surfaces through serrated metal teeth on the underside of the head of the first component and on the inside surface of the second component which embed into each metal surface as a fastener is tightened. In one embodiment, the fastener is a nut and bolt combination, and in another embodiment the fastener is a two-part rivet. A sealing material circumferentially outward from the teeth on both the first component and second component creates an air-tight and water-tight seal around the teeth, protecting the bonding location from air and water infiltration from the outside. The second component also has an internal seal, sealing around the shank of the first component to prevent axial infiltration of air or water along the shank and protecting the bonding locations from corrosion from contaminants entering along that route.
