Abstract
"FIXADOR DE ENROSCAMENTO ANTITRANSVERSAL APERFEIçOADO". Um fixador de enroscamento antitransversal incluindo uma parte eixo tendo uma primeira parte extremidade de avanço com uma primeira extremidade, uma primeira parte eixo rosqueado tendo uma primeira parte eixo rosqueado afilado se estreitando no sentido da primeira extremidade, e roscas de parafuso da primeira parte eixo rosqueado afilado tem um ângulo de flanco mairo do que um ângulo de flanco das roscas de parafuso de uma primeira parte eixo rosqueado não-afilado. As roscas de parafuso da primeira parte eixo rosqueado afilado têm, de preferência, o mesmo passo geométrico que as roscas de parafuso da primeira parte eixo rosqueado não-afilado. Uma parte eixo cilíndrico tendo um diâmetro menor do que uma diâmetron grande da primeira parte eixo rosqueado pode ser disposta entra a primeira extremidade da parte eixo e a primeira parte eixo rosqueado. A primeira parte extremidade de avanço pode ter uma parte ponta com uma superfície parcialmente substancialmente curva, ou uma superfície de engate de ferramenta de introdução."PERFECTED ANTITRANSVERSAL THREADING FIXER". An anti-cross threaded fastener including a shaft part having a leading end first part with a first end, a threaded shaft first part having a tapered threaded shaft first part narrowing towards the first end, and screw threads of the threaded shaft first part tapered angle has a larger flank angle than a flank angle of the screw threads of a first part non-tapered threaded shaft. The screw threads of the first part of the tapered threaded shaft preferably have the same geometric pitch as the screw threads of the first part of the tapered threaded shaft. A cylindrical shaft part having a diameter smaller than a large diameter of the first threaded shaft part can be arranged between the first end of the shaft part and the first threaded shaft part. The first lead end portion may have a tip portion with a partially substantially curved surface, or an insertion tool engagement surface.
