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.
