Un perno de techo alargado que presenta una perforacion central que se extiende axialmente y que forma un extremo guía en un extremo del mismo. El extremoguía incluye un par de elementos de apoyo torneados que se extienden axialmente, cada uno de los cuales incluye una cara de apoyo que entra en contacto con unapunta de perforacion en extremos opuestos del mismo, para soportar la punta de perforacion durante la perforacion. La punta de perforacion se extiende a travésde dicho extremo guía y está asegurada a los elementos de apoyo mediante soldadura autogena, soldadura blanda o soldadura fuerte. La perforacion se abre haciael exterior de dicho perno en dicho extremo guía o en forma adyacente al mismo.
