An expandable sealant is provided for a fastener including a threaded defining surface. The fastener includes the expandable sealant as a coating adhered to at least a portion of the thread-defining surface to lock the fastener in place and to expand to fill space between the thread-defining surface of the fastener and an aperture through which the fastener is passed to seal the aperture to prevent fluid and gases from passing therethrough.

La présente invention concerne un produit d~étanchéité expansible pour une fixation dont une surface définit un filet. La fixation comprend le produit d~étanchéité expansible sous la forme d~un enduit collé à au moins une partie de la surface définissant un filet afin d~immobiliser la fixation et de se dilater afin de remplir l~espace entre la surface définissant le filet de la fixation et une ouverture au travers de laquelle la fixation est passée pour étanchéiser l~ouverture afin d~empêcher les fluides et les gaz de la traverser.
