Abstract
The invention relates to a metal fastener that makes it possible to ensure an electrically conductive surface along the entire thickness of structural elements to be assembled. The fastener thereby comprises a head and a smooth shank extending along an axis of revolution, characterized in that the shank comprises at least one conductive portion and one lubricating portion disposed along the axis of revolution of the fastener along at least one length of the shank. The inventive fastener makes it possible to ensure a conductive surface in the entire thickness of the structure in which it is installed.The inventive fastener is particularly intended for aeronautical applications.
