Abstract
"PARAFUSO PROVIDO COM ROSCA DE APERTO AUTOMáTICO". Parafuso provido com rosca laminada de aperto automático, no qual, em uma pluralidade de locais ao longo de sua extensão, a dita rosca é deformada em relação à seção transversal de rosca normal de modo que o diâmetro externo de rosca seja reduzido pela compressão radial das porções de rosca limitadas, a área da seção transversal de rosca sendo substancialmente idêntica à da rosca não deformada. Ao manter a inclinação dos flancos de rosca, a seção transversal de rosca é simetricamente alargada na região externa e reduzida na região interna adjacente, a transição da seção transversal de rosca alargada para reduzida assentando-se aproximadamente no centro do respectivo flanco de rosca, e a porção de rosca limitada se estende sobre duas partes de um filete de rosca de tal modo que resultem duas porções de rosca simetricamente opostas, cada qual de aproximadamente 1/6 do filete de rosca.
