Fastener using lubricated interference fit

A method for installing a metallic fastener a hole passing through at least two structural elements, the fastener comprising an enlarged head and a shaft having an external diameter D1 before installation that is greater than an internal diameter D3 of the hole, said shaft comprising a conductive surface,

• wherein at least the conductive surface includes a coating with a lubricating layer comprising a mixture of at least one polyolefin and one polytetrafluoroethylene, and wherein during the installation, inserting the fastener into the hole wherein the lubricating layer has a composition determined so as to have sufficient adherence to prevent its abrasion by manual manipulation of the fastener and to be weak enough to be at least partly stripped from the conductive surface during the interference fit insertion of the fastener and comprises at least 80% by weight of polyolefin and polytetrafluoroethylene, and during a step of inserting the shaft of the fastener into the structure through an interference fit, the lubricating layer is partly stripped from the shaft of the screw.
