Beschreibung
Zusammenfassung:	An electromagnetic effect suppressing termination part (50) for a fastener (40) formed of a metallic material, the fastener having a head (42), a shank (44), and a male threaded portion (46) 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 (70) includes an outer wall (72), and a frustoconical wall (74) 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 (68) 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.
