The invention relates to a method for installing metallic fastener (10; 40) for the interference fit assembly of at least two structural elements (20, 22) comprising a through hole, the fastener comprising an enlarged head (12; 42), a shaft (14; 44) having an external diameter before installation that is greater than an internal diameter of the hole, said shaft comprising a conductive surface (26; 56). Before installation, at least the conductive surface (26; 56) is coated with a lubricating layer (30), which comprises a mixture of at least one polyolefin and one polytetrafluoroethylene, for example, having sufficient adherence to prevent its abrasion by manual manipulation of the fastener and being weak enough to be at least partly stripped from the conductive surface during the interference fit assembly of the fastener. The invention is applicable to the assembly of aircraft structures.
