Abstract

Method for increasing the resistance to extraction of a screw 20, which is screwed into a receiving substrate 35, which method involves unscrewing the screw and removing it from the hole, and then introducing a spiral element 140 with a projecting triangular profile into the old threads and screwing the screw into the hole, the spiral element engaging in the hole and the screw with its threads engaging in the spiral element and forcing the triangular profile into the material. The lower end 146, 182 of the spiral element is designed so that it can be detachably made to engage with a tool 160, which is introduced into the centre of the spiral element, it being possible to exert the force required for screwing the spiral element in the hole on the bottom end of the spiral element. The spiral element is made of moderately flexible material (as defined herein), the spiral element being bent inwards and back along the shaft at the one end in order to form a drive pin 182, and the spiral element preferably being designed to narrow towards the end forming the drive pin. The screw can thereby deform the spiral element and force the spiral element down out of its way. A tool for inserting the spiral element is also described.
