ELECTROMAGNETIC EFFECT PROTECTIVE FASTENER WITH FRANGIBLE COLLAR

The invention relates to an electromagnetic effect protective fastener with a frangible collar. The electromagnetic effect suppressing termination part is provided for a fastener formed of a metallicmaterial, 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. 本公开涉及具有易碎套环的电磁效应防护紧固件。一种电磁效应抑制端接部件，该电磁效应抑制端接部件用于由金属材料形成的紧固件，该紧固件具有头部、杆部以及与
