SLEEVED FASTENER ASSEMBLY

摘要

A conductive fastener assembly, system, and method are described. The fastener assembly includes a nut having a counterbore formed therein. The counterbore is formed to maintain a sufficient gap between the nut and the protruding end of a fastener sleeve. The nut with the counterbore improves the conductive fastener system such that the need for a solid copper grid and a cap seal is reduced or eliminated.

主权项

1. A method of preparing a conductive sleeved fastening system for use, comprising:
providing a fastener having a fastener head, a fastener shank extending from said fastener head, and a fastener sleeve provided on said fastener shank and a fastener sleeve flare on said fastener sleeve; preparing a nut configured to attach to the fastener shank, by forming a counterbore therein, the counterbore having:
a counterbore diameter sized to maintain a radial gap between an inward-facing surface of the counterbore and an outer surface of the fastener sleeve; anda counterbore depth sized to maintain an axial gap between a distal end of the fastener sleeve and a bottom surface of the counterbore.
