Title (EN) COATED FASTENERS WITH CONFORMING SEALS
(FR) ATTACHES REVÊTUES AVEC JOINTS D'ÉTANCHÉITÉ CONFORMES
Abstract:
(EN) A pin member (12) for a fastener includes an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the bearing surface of the head, and a threaded portion located at the second end of the elongated shank. The pin member can be fully coated with a coating. A conformable seal element (24) is attached to the pin member, which is adapted to fill the microscopic voids between the bearing surface of the head of the pin member and the surrounding structure under the axial load exerted by the fastener during installation. The seal element can be separate and distinct from the pin member. The seal element can be attached to the pin member for the sake of convenience, but the seal element can deform independently of the pin member and the surrounding structure in response to the forces exerted by the fastener.
(FR) Un élément de broche (12) destiné à une attache comprend une tige allongée présentant une première extrémité, une seconde extrémité opposée à la première extrémité, une partie de tige cylindrique présentant une surface extérieure, une tête située au niveau de la première extrémité de la tige allongée, la tête comprenant une surface d'appui située sur la surface d'appui de la tête, et une partie filetée située au niveau de la seconde extrémité de la tige allongée. L'élément de broche peut être complètement revêtu d'un revêtement. Un élément de joint d'étanchéité conformable (24) est fixé à l'élément de broche, qui est conçu pour remplir les vides microscopiques entre la surface d'appui de la tête de l'élément de broche et la structure environnante sous la charge axiale exercée par l'attache pendant l'installation. L'élément de joint d'étanchéité peut être séparé et distinct de l'élément de broche. L'élément de joint d'étanchéité peut être fixé à l'élément de broche pour plus de commodité, mais l'élément de joint d'étanchéité peut se déformer indépendamment de l'élément de broche et de la structure environnante en réponse aux forces exercées par l'attache.
