Abstract

CAVILHA. Uma cavilha na qual uma parte guia (116) de pequeno diâmetro é formada na parte de extremidade distal de uma parte de haste (15) e estrias (31) tendo uma configuração de rosca na direção invertida em relação à estria (30) formada sobre uma parte de diâmetro constante (115) é formada. Quando a cavilha (1) é inserida obliquamente no interior de uma porca (100) e a estria entra em engate com uma parte de rosca fêmea (105) da porca (100), um efeito de flutuação sobre a cavilha (1) é geado, e a cavilha (1) não pode ser atarraxada na porca (100) salvo ser é disposta em uma postura de aperto apropriada. Conseqúentemente, uma condição aferrada e engripada da cavilha com a porca 100 pode ser prevenida positivamente. Se a estria (31) é formada em um parafuso de rosca dupla tendo uma configuração de rosca na direção invertida o efeito pode ser adicionalmente intensificado.
