A pre-load indicating washer (40) for properly tensioning a joint held together by an externally threaded member and an internally threaded member. The pre-load indicating washer (40) has a plurality of protuberances (42), struck and partially sheared from the annular body of the washer (40), which are pushed under load back into a corresponding number of indentations (46) in the annular body which are formed when the protuberances (42) are formed. The protuberances (42) of the pre-load indicating washer (40) are curved in outline with no portion of the protuberances (42) extending radially outward beyond the outer periphery of the bearing surface of an externally threaded member when the pre-load indicating washer (40) is positioned adjacent the externally threaded member, or radially outward beyond the outer periphery of the bearing surface of an internally threaded member when the pre-load indicating washer (40) is positioned adjacent the internally threaded member.

La présente invention concerne une rondelle (20) d'indication de charge préalable permettant de soumettre à une tension appropriée un raccord tenant au moyen d'un élément à filetage mâle et d'un élément à filetage femelle. La rondelle (20) d'indication de charge préalable comporte une pluralité de protubérances (26), embouties dans, et partiellement découpées du corps annulaire de la rondelle (20), et qui, sous l'effet de la charge, sont refoulées dans un nombre correspondant d'évidements (30) du corps annulaire qui se forme en même temps que les protubérances (26). Le contour d'incurvation des protubérances (26) des rondelles (20) d'indication de charge préalable ne s'inscrit dans aucune partie des protubérances (26) situées radialement au-delà du pourtour extérieur de la surface portante d'un élément à filetage mâle lorsque la rondelle (20) d'indication de charge préalable s'applique contre l'élément à filetage mâle, ou radialement au-delà du pourtour extérieur de la surface portante d'un élément à filetage femelle lorsque la rondelle (20) d'indication de charge préalable s'applique contre l'élément à filetage femelle.
