Abstract

Procédé servant à accroître la résistance à l'extraction d'une vis (20) vissée dans un substrat récepteur (35), consistant à dévisser la vis et à l'extraire du trou, à positionner dans le filetage un organe spiralé (140) présentant un profil pointu orienté vers l'extérieur, et à revisser la vis dans le trou, l'organe spiralé s'engageant dans le trou et la vis se vissant dans l'organe spiralé en enfonçant le profil pointu dans le substrat. L'extrémité du fond (146 ou 182) de l'organe spiralé est façonnée de manière à pouvoir s'engager de manière libérable dans un outil (160) introduit à travers le centre de l'organe spiralé et permettant d'appliquer, depuis l'extrémité inférieure de l'organe spiralé, la force nécessaire pour visser l'organe dans le trou. L'organe spiralé se compose d'un matériau malléable et est retourné vers l'intérieur et en arrière le long de l'axe à une extrémité pour former un ergot d'entraînement (182), et est de préférence conique en direction de l'extrémité présentant l'ergot d'entraînement. L'organe spiralé peut ainsi être déformé par la vis et l'extrémité inférieure de l'organe peut être écartée du chemin de la vis par celle-ci. Est également décrit un outil servant à introduire l'organe spiralé.
