Abstract

Patente de Invenção: <B>"SISTEMA PRENDEDOR COM REBAIXO DE FENDA CRUZADA E BROCA DE FENDA CRUZADA"<D>. Sistema prendedor aperfeiçoado que inclui um pino rosqueado e uma broca. O pino contém um rebaixo em uma extremidade rosqueada do pino para receber a broca, prendendo assim o pino contra rotação durante a aplicação de uma porca no pino. Em uma concretização, o rebaixo inclui um par de fendas de interseção substancialmente perpendiculares que se estendem completamente através de uma face de extremidade da extremidade rosqueada do pino, com uma abertura localizada na interseção das fendas. Uma pluralidade de estrias é localizada em uma extremidade da broca para engatar as fendas do rebaixo. As estrias são orientadas na broca para refletir a configuração do rebaixo. Adicionalmente, um piloto estende-se a partir das estrias na extremidade da broca para engatar a abertura do rebaixo e centralizar a broca durante o uso.
