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.
Claims24
A metal fastener comprising an expanded head and a smooth shank extending in an axis of revolution, wherein the shank has a shank surface that comprises at least one conductive portion and at least one lubricating portion, disposed continuously along the axis of revolution of the fastener, wherein the shank at least one conductive portion and at least one lubricating portion are disposed continuously and parallel along the axis of revolution of the fastener, wherein the smooth shank comprises a cylindrical shaft, and the at least one conductive portion is a bare metal portion.
