Abstract

Un perno de conexión (1) para aprietes repetidos más a allá del punto de fluencia cuyo perno (1) comprende una cabeza (2) y un vástago, cuyo vástago está provisto de una rosca, de modo que dicha cabeza (2) de dicho perno de conexión (1) está provista de al menos una marca de indicación (9) en una posición angular mutua definida fija con respecto a al menos un signo de indicación (10), cuyo signo (10) está dispuesto en el extremo libre del vástago (5) con relación al eje geométrico (q-q) de rotación del perno (1). Este sistema de marcado permite determinar exactamente el daño en dicho perno (1) y decidir acerca de la ulterior capacidad de dicho perno (1) para ser usado la siguiente vez sin riesgo alguno de destrucción ni de disminución de la calidad de una unión.
