直径与螺距系列(摘自GB/T 5796.2-2005)
注:优先选用第一系列直径,其次选用第二系列直径;新产品设计中,不宜选用第三系列直径;标注*的螺距为优选螺距。如果需要使用规定以外的螺距,则选用表中邻近直径所对应的螺距。
标准梯形螺纹的标记应由螺纹特征代号“Tr”、公称直径和导程的毫米值、螺距代号“P”和螺距毫米值组成。公称直径与导程之间用“×”号分开;螺距代号“P”和螺距值用圆括号括上。对单梯形螺纹,其标记应省略圆括号部分(螺距代号“P”和螺距值)。对标准左旋梯形螺纹,其标记内应添加左旋代号“LH”。

内螺纹推荐公差带
注:中等用于一般用途螺纹,粗糙用于制造螺纹有困难的场合。如果不能确定螺纹旋合长度的实际值,推荐按中等旋合长度组N选取螺纹公差带。螺纹尺寸代号与中径公差带代号间用“-”分开。
| 公差精度 | 中径公差带|N | 中径公差带|L |
|---|---|---|
| 中等 | 7H | 8H |
| 粗糙 | 8H | 9H |

多线螺纹的中径公差修正系数
注:多线螺纹的中径公差等于具有相同螺距单线螺纹的中径公差乘以修正系数。
