Metal fastener
First Claim
1. A metal fastener comprising an expanded head and a smooth shank extending in an axis of revolution, characterized in that the shank comprises at least one portion treated by anode oxidation and at least one lubricating portion, wherein the at least one portion treated by anode oxidation and at least one lubricating portion are disposed continuously along the axis of revolution (A) of the fastener and wherein the at least one lubricating portion has a side portion disposed continuously along the axis of revolution and anode oxidation extends in a circumferential direction away from the side portion.

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.
