Abstract
The invention concerns a metal attachment for providing an electrically conductive surface through the entire thickness of structural elements to be assembled. The attachment thereby comprises a head (12)and a smooth shank (14) extending along an axis of revolution, characterized in that the shank comprising at least one conductive portion (24) and one lubricating portion (22) disposed along the axis of revolution of the attachment along at least one length of the shank. The attachment according to the invention provides a conductive surface through the entire thickness of the structure in which it is installed. The attachment according to the invention is intended, in particular, for aeronautical applications.
