FASTENER USING LUBRICATED INTERFERENCE FIT

The invention relates to a metallic fastener (10; 40) for assembly by interference fit of at least two structural elements (20, 22) comprising a through drilling, the fastener comprising an enlarged head (12; 42), a shaft (14; 44) having an external diameter (D1) before installation that is greater than an internal diameter (D3) of the bore, said shaft (14; 44) comprising a conductive surface (26; 56). Before installation, at least one conductive surface (26; 56) is covered with a lubricating layer (30) having sufficient adherence to prevent its abrasion by manual manipulation of the fastener (10; 40) and sufficiently weak to be at least partially torn from the conductive surface (26; 56) during mounting by interference fit of the fastener (10; 40), a mixture of at least one polyolefin and one polytetrafluoroethylene for example. The invention also relates to a method for obtaining such an fastener (10;40) and an installation method of such a fastener (10; 40) in a structure (22; 24). The invention has applic
