The invention concerns a tool for removing fastening members, such as nuts and studs. The tool comprises an elongate body member (30) with first and second ends, the first end having means (31') for deforming an end face of the fastening member to provide an area of purchase thereon; and means (44) to cause rotation of the fastening member to unscrew the fastening member from the structure. Also within the scope of the present invention is a locating means (38') for locating the first end of the body member (30') with respect to the end face of the fastening member as well as a method for enabling removal of fastening members by action upon an end face of a fastening member.

Cet outil comprend un corps (30) allongé doté de première et seconde extrémités, la première extrémité possédant un organe (31') permettant de déformer une face terminale de l'élément de fixation afin d'y créer une surface de traction, et un organe (44) faisant tourner l'élément de fixation afin de le dévisser de la structure. Cette invention porte également sur un organe (38') de positionnement qui positionne la première extrémité du corps (30') par rapport à la face terminale de l'élément de fixation, ainsi que sur un procédé permettant de retirer les éléments de fixation en actionnant leur face terminale .
