Tabla de roscas métricas: dimensiones y detalles
Introducción
La tabla de roscas métricas, viene definida por la ISO 724, que especifica las dimensiones básicas de las roscas métricas de acuerdo con ISO 261. Las dimensiones se refieren al perfil básico de acuerdo con ISO 68.
El paso varía de grueso a extrafino con hasta 5 pasos diferentes para algunas dimensiones. El ángulo de la rosca es de 60 grados y la profundidad de la rosca es de 0,614 x paso.
Roscas métricas – Roscas más gruesas
La siguiente tabla de roscas métricas, indica algunos de los hilos gruesos más utilizados hasta el tamaño M 68. Tenga en cuenta que la norma ISO 724 especifica hilos hasta M 300. La siguiente tabla no está completa.
- Para roscas métricas, el paso es la distancia entre roscas.
Roscas métricas – Roscas más finas
Es común designar las roscas finas métricas con la M mayúscula más una indicación de su diámetro exterior nominal y su paso:
Tamaño M x paso (Ejemplo: M10x1,5)
Esta tabla de roscas métricas indica los hilos más finos que se utilizan normalmente hasta el tamaño M 100. Tenga en cuenta que la norma ISO 724 especifica hilos hasta M 300.
