A fastener system includes a screw or bolt having two interleaved helical threads which bracket a helicoil. The helicoil expands and torques by various means to maintain hold and purchase between the screw coil combination and the substrate into which the screw and helicoil are inserted even when the substrate recedes a significant distance from the screw and helicoil combination. The two interleaved threads hold the coil and prevent it from rolling over the threads in high load applications.
Système de fixation comprenant une vis ou un boulon comportant deux filets hélicoïdaux entrelacés qui encadrent un Helicoil. L'Helicoil se dilate et fournit un couple par divers moyens de façon à maintenir la prise et l'appui entre une combinaison de spirale de vis et le substrat dans lequel on insère la vis et l'Helicoil, même si le substrat est éloigné à une distance important de la combinaison de vis et de l'Helicoil. Les deux filets hélicoïdaux retiennent la spirale et l'empêchent de s'enrouler autour des filets dans les applications à charges élevées.
