Abstract
An electromagnetic effect suppressing termination part for a fastener formed of a metallic material, the fastener having a head, a shank, and a male threaded portion opposite the head, has a metallic core coated by a layer of dielectric material. An internal bore of the termination part includes an inner wall, a counterbore hole, and a cavity disposed therebetween. An outer surface includes an outer wall, and a frustoconical wall positioned proximally relative to the outer wall, the frustoconical wall extending radially outwardly from the outer wall and having an included angle of less than approximately 90 degrees. A seal is disposed in the counterbore hole, and the frustoconical wall is configured so that a compressive force applied to the frustoconical wall deforms the inner wall to conform to the male threaded portion of the fastener and deforms the seal to fill the cavity.
