Abstract

Un tornillo (1) de alta resistencia presenta una cabeza (2) y un segmento de rosca (5) con una rosca (6) con un extremo de rosca (9) que señala hacia el lado opuesto de la cabeza (2) en dirección axial. El segmento de rosca (5) presenta una zona de menor dureza (12) que parte del extremo de rosca (9) y se extiende en dirección axial, presentando la zona de menor dureza (12) una dureza reducida en comparación con una zona central (11) axial del segmento de rosca (5). (Figura 1).
