Abstract
"PARAFUSO DE TETO AUTO-PERFURADOR". A presente invenção se refere a um parafuso de teto alongado tendo um furo central que se estende axialmente, definindo uma extremidade guia em uma de suas extremidades. A extremidade guia inclui um par de elementos de apoio que se estende axialmente, formados mediante usinagem, cada um dos quais incluindo uma face de apoio para engate com uma ponta de broca em lados opostos da mesma, para suportar a ponta de broca durante a perfuração. A ponta de broca se estende transversalmente à dita extremidade guia, sendo presa aos elementos de apoio mediante soldagem ou com solda forte. O furo se abre para fora do dito parafuso na dita extremidade guia ou de modo adjacente à dita extremidade guia.
