CONDUCTIVE SLEEVED FASTENER ASSEMBLY

摘要

The present disclosure describes a conductive fastener assembly, system, and method, wherein the fastener assembly comprises a fastener, a fastener sleeve, a nut, and a lubricant coating. The lubricant coating is deposited on a distal portion of a fastener shank and is omitted from the rest of the fastener. To overcome the stresses placed on the fastener sleeve by the insertion of the fastener shank largely devoid of a lubricant coating, the fastener sleeve is reinforced by one or more of an increased thickness, a high-strength alloy, and a soft metal coating.

主权项

1. A conductive sleeved fastener assembly, comprising:
an electrically-conductive fastener having a fastener head and a fastener shank extending from said fastener head, the fastener shank further comprising an attachment portion located at a distal end of the fastener shank; an electrically-conductive fastener sleeve configured to receive said fastener shank of said fastener, the fastener sleeve having a fastener sleeve flare at a top end of said fastener sleeve; a nut configured to attach to the attachment portion of the fastener; and a lubricant coated on the fastener where the attachment portion is configured to engage the nut, wherein the lubricant is omitted from the fastener shank and fastener head.
