Varas e parafusos

A Essentra Components possui ferramentas manuais especializadas, projetadas para fins específicos, como "rethreaders" manuais. Temos ferramentas para extrair e instalar pastilhas roscadas, bem como para identificar e verificar tamanhos de rosca.

Esta gama de Anilhas Cativas tem uma rosca muito fina no seu interior. Isto significa que podem ser aparafusadas, e uma vez atingida a rosca, a anilha não se separa do parafuso cativo.

Como instalar um conjunto de parafuso cativo e anilha:
1) Coloque o parafuso cativo no orifício do painel.
2) Enrosque a anilha no parafuso, para além da parte roscada do parafuso, que retém o parafuso no painel.

As anilhas são feitas em aço inoxidável que oferece boa resistência à corrosão e boa maquinabilidade. O material é muito utilizado para construção civil e aplicações no setor automóvel.
