螺 纹 攻 牙 钻 孔 径 和 滚 造 径 对 照 表

本表所推选之钻头孔径，是针对攻牙加工时，能够很容易的了解钻孔直径；而依据市售之标准钻头所选定的。在使用钻头的情况下，由于钻头的形状及尺寸、精度、被钻孔之材质等，对于所钻孔的尺寸、精度有很大的影响，所以使用本表之钻孔径，若有不当之处，应视实际状况适当的变更钻头直径。本表是依据2级牙制订。公 制 粗 螺 纹公 制 细 螺 纹公 制 迫 牙 丝 攻 钻 孔 径美 制 迫 牙 丝 攻 钻 孔 径英 制 螺 纹

钻孔攻牙孔径对照表【免费下载】

钻孔攻牙孔径对照表【免费下载】

标准公制螺母攻牙要钻个小于螺纹大径的孔来攻牙。

这个孔的大小就是螺纹小径到螺纹中径。如何确认孔径大小就要参照对照表啦！

公制粗螺纹 公制细螺纹
