Abstract

Vis autoperforante et autotaraudeuse partiellement cémentée. Elle comporte une tige 22 dont un tronçon extrême, comprenant une pointe 28 et des rainures 30 de perçage, quelques filets 32 et une rainure 34 de taraudage, est cémenté. A cet effet, une couche métallique sensiblement imperméable aux gaz est appliquée sur la partie de la vis ne devant pas etre cémentée, puis la vis est exposée à un gaz réagissant avec cette couche métallique de manière à provoquer une cémentation de l'acier du tronçon devant être durci. Domaine d'application : vis autoperforantes et autotaraudeuses.Partially hardened self-drilling and self-tapping screw. It comprises a rod 22 of which an end section, comprising a point 28 and drilling grooves 30, a few threads 32 and a tapping groove 34, is case-hardened. To this end, a metal layer substantially impermeable to gases is applied to the part of the screw which does not have to be case hardened, then the screw is exposed to a gas reacting with this metal layer so as to cause case hardening of the steel of the section. to be hardened. Field of application: self-drilling and self-tapping screws.
