An electromagnetic effect suppressing termination part is provided for a fastener formed of a metallic material, the fastener having a head, a shank, and a threaded portion opposite the head. The termination part includes a main body defining an internally threaded portion configured to threadably receive the threaded portion of the fastener, the internally threaded portion defining a thread major diameter. A collar is coupled to a distal end of the main body by a frangible web, wherein the main body, collar, and frangible web are formed of a metallic core coated by a layer of dielectric material. The frangible web, when broken, presents an exposed portion of the metallic core, wherein the frangible web includes an inner surface radially outwardly offset from the thread major diameter of the internally threaded portion by a setback distance.
