公英制螺纹对照表
英制、公制对照表
英寸制统一螺纹，在英寸制国家广泛采用，该类螺纹分三个系列：粗牙系列UNC，细牙系列UNF，特细牙系列UNFF，外加一个定螺距系列UN。
标注方法：螺纹直径—每英寸牙数系列代号—精度等级
示例：粗牙系列 3/8—16 UNC—2A 细牙系列 3/8—24 UNF—2A 特细牙系列 3/8—32 UNFF—2A 定螺距系列 3/8—20 UN—2A 第一位数字3/8表示螺纹外径，单位为英寸，转换为米制单位mm要乘以25.4，即3/8×25.4=9.525mm；第二、三位数字16、24、32、20为每英寸牙数(在25.4mm长度上的牙数)；第三位以后的文字代号UNC、UNF、UNFF、UN为系列代号，最后两位2A为精度等级。
在统一螺纹标准中规定，一个公称尺寸可有不同的螺距，如1/2就有13牙、16牙、20牙、32牙之分，标准规定13牙为粗牙，20牙为细牙，28牙为超细牙；16牙和32牙都称为恒定螺距，与粗牙、细牙没什么不同。

公制螺纹标准对照表
公制螺纹标准对照表螺纹是机械连接中常见的一种连接方式，它通过螺纹的搭接，实现零件的连接和固定。
在工程设计和制造中，常用的螺纹标准有英制螺纹和公制螺纹两种。
本文将重点介绍公制螺纹标准对照表，以便工程师和制造人员在实际工作中能够准确选择和应用公制螺纹。
1. M 系列螺纹。
M 系列螺纹是最常见的公制螺纹之一，它采用米制单位表示螺纹直径。
M 系列螺纹的标准是 DIN 13，它包括了M1.6至M64的多个规格，每个规格都有着特定的螺距和公差要求。
M 系列螺纹通常用于机械设备的组装和固定，广泛应用于各种行业。
2. MF 系列螺纹。
MF 系列螺纹是一种特殊的公制螺纹，它的螺距和公差与M 系列螺纹相同，但是其螺纹直径采用的是毫米和英寸的混合表示。
MF 系列螺纹适用于需要与英制螺纹配合使用的场合，它的标准是 ISO 724。
3. MJ 系列螺纹。
MJ 系列螺纹是一种特殊的大径公制螺纹，它的螺距和公差与M 系列螺纹相同，但是其螺纹直径比M 系列螺纹大，通常用于大型机械设备的连接和固定。
MJ 系列螺纹的标准是 ISO 5855。
4. PG 系列螺纹。
PG 系列螺纹是一种用于管道连接的公制螺纹，它的标准是 DIN 40430。
PG 系列螺纹采用的是管螺纹，其螺距和公差与M 系列螺纹有所不同，适用于管道连接和密封。
5. TR 系列螺纹。
TR 系列螺纹是一种特殊的公制螺纹，它的标准是 DIN 103。
TR 系列螺纹采用的是圆锥螺纹，其螺距和公差与M 系列螺纹有所不同，适用于需要良好密封性能的场合。
6. 其他特殊螺纹。
除了上述常见的公制螺纹系列外，还有一些特殊的公制螺纹，如圆锥管螺纹、汽车管螺纹等，它们都有着特定的标准和应用范围，需要根据实际情况进行选择和应用。
总结。
公制螺纹标准对照表是工程设计和制造中的重要参考资料，它能够帮助工程师和制造人员准确选择和应用合适的公制螺纹，确保零件的连接和固定符合要求。
在实际工作中，我们需要根据具体的需求和要求，选择合适的公制螺纹标准，合理设计和制造螺纹连接，确保其可靠性和稳定性。

公制细螺纹规格对照表
公制细螺纹规格对照表公制细螺纹是机械工程中常用的螺纹规格，广泛应用于各种机械设备和工艺中。
公制细螺纹规格主要包括螺纹直径、螺距和牙深等参数。
下面将介绍一些常见的公制细螺纹规格及其对照表。
1. 螺纹直径：螺纹直径是螺纹规格的基本参数之一，定义为螺纹轮廓的最大直径。
常见的公制细螺纹直径有M1.0、M1.2、M1.4、M1.6、M2.0等，其中M表示公制（Metric），后面的数字表示螺纹直径的大小，单位为毫米（mm）。
2. 螺距：螺距是螺纹规格的另一个重要参数，定义为同一轴向上相邻两个螺纹绕旋转一周时，螺纹前进的距离。
常见的公制细螺纹螺距有0.25mm、0.3mm、0.35mm、0.4mm等。
螺距的大小与螺纹的紧密程度有关，螺距越小，螺纹间的间隔越密集，相应的螺纹间的接触面积也更大。
3. 牙深：牙深是指螺纹切口的深度，通常用螺纹高度来表示。
螺纹高度是螺纹切口到螺纹轴线的距离。
公制细螺纹的牙深规格有不同的设计，常见的有1D、1.5D、2D等。
其中D表示公制螺纹直径的倍数，例如1D表示螺纹高度等于螺纹直径，2D表示螺纹高度等于两倍螺纹直径。
下面是公制细螺纹规格的对照表：螺纹规格直径（mm）螺距（mm）牙深（D）M1.0 1.0 0.25 1DM1.2 1.2 0.25 1DM1.4 1.4 0.3 1DM1.6 1.6 0.35 1DM2.0 2.0 0.4 1DM2.5 2.5 0.45 1.5DM3.0 3.0 0.5 2DM4.0 4.0 0.7 2DM5.0 5.0 0.8 2DM6.0 6.0 1.0 2D以上仅为常见的公制细螺纹规格，实际使用中还有更多规格可以选择。
公制细螺纹由于具有易于制造、安装方便、拧紧力矩小等优点，被广泛应用于机械工程领域。
正确选择合适的螺纹规格，对于机械设备的装配和使用十分重要。
