Abstract

Método para realizar un tornillo auto-perforante, de corte de rosca hecho de acero resistente a la corrosión y que tiene unas porciones externas de perforación cementadas, que incluye las operaciones que consisten en realizar sobre la parte del tornillo formado que no ha de ser cementada una capa metálica sustancialmente impermeable a los gases y en someter el tornillo a un gas capaz de reaccionar con la aleación ferrosa para producir la cementación del acero en esta parte del tornillo que ha de ser cementada.
