螺纹是一种常见的连接方式，常用于机械和结构中。
这个规格表可以帮助人们选择适合他们需要的螺纹。
修正后的表格清晰地显示了不同公称直径和螺距的基本尺寸。
这些尺寸可以帮助人们选择正确的螺纹，以确保它们能够正确地连接和承受所需的负载。
使用这个规格表时，人们需要了解他们需要连接的材料和所需的负载。
然后，他们可以查找适合他们需要的螺纹规格。
螺纹规格的选择非常重要，因为错误的规格可能会导致连接的松动或破坏，从而导致机械或结构的故障。
因此，使用这个规格表可以帮助人们选择正确的螺纹规格，以确保他们的连接是牢固和可靠的。
螺纹是指在圆柱或圆锥表面上，沿着螺旋线所形成的具有规定牙型的连续凸起。
根据不同的特征，螺纹可以分为圆柱螺纹和圆锥螺纹，同时也可以按照不同的标准进行分类。
圆柱螺纹分为普通螺纹、美标统一螺纹、非螺纹密封的管螺纹、梯形螺纹和其他螺纹。
普通螺纹是指代号为M，牙形角为60°，基本牙形为平顶的螺纹，其精度等级为内螺纹4~8级，外螺纹3~9级。
美标统一螺纹的代号为UNC、UNF、UNEF、UN、UNS，牙形角也为60°，基本牙形为平顶，精度等级为内螺纹1B~3B，外螺纹1A~3A。

(完整版)最新GB公制螺纹标准
普通螺纹标准规格表螺纹基本知识一、螺纹的名词术语螺纹：在圆柱或圆锥表面上，沿着螺旋线所形成的具有规定牙型的连续凸起。
圆柱螺纹/圆锥螺纹；外螺纹/内螺纹；右旋螺纹/左旋螺纹。
右旋螺纹：顺时针旋转时选入的螺纹。
左旋螺纹：逆时针旋转时选入的螺纹。
完整螺纹：牙顶和牙底具有完整形状的螺纹。
不完整螺纹：牙底完整而牙顶不完整的螺纹。
螺尾：向光滑表面过渡的牙底不完整的螺纹。
有效螺纹：由完整螺纹和不完整螺纹组成的螺纹，不包括螺尾。
公称直径：代表螺纹尺寸的直径。
大径：外螺纹的顶径、内螺纹的底径。
小径：外螺纹的底径、内螺纹的顶径。
中径：一个假想圆柱或圆锥的直径，该圆柱或圆锥的母线通过牙型上沟槽和凸起宽度相等的地方。
单一中径：牙型上沟槽宽度等于1/2基本螺距的地方。
作用中径：在规定的旋合长度内，恰好包容实际螺纹的一个假想螺纹的中径，这个假想螺纹具有理想的螺距、螺纹半角、及牙型高度，并在牙顶和牙底留有间隙，不与实际螺纹大、小径发生干涉。
牙型角：在螺纹牙型上，两相邻牙侧间的夹角。
螺距：相邻两牙在中径线上对应两点间的轴向距离。
螺纹精度：由螺纹公差带和旋合长度共同组成的衡量螺纹质量的综合指标。

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。

GB公制螺纹标准资料
普通螺纹标准规格表螺纹基本知识一、螺纹的名词术语螺纹：在圆柱或圆锥表面上，沿着螺旋线所形成的具有规定牙型的连续凸起。
圆柱螺纹/圆锥螺纹；外螺纹/螺纹；右旋螺纹/左旋螺纹。
右旋螺纹：顺时针旋转时选入的螺纹。
左旋螺纹：逆时针旋转时选入的螺纹。
完整螺纹：牙顶和牙底具有完整形状的螺纹。
不完整螺纹：牙底完整而牙顶不完整的螺纹。
螺尾：向光滑表面过渡的牙底不完整的螺纹。
有效螺纹：由完整螺纹和不完整螺纹组成的螺纹，不包括螺尾。
公称直径：代表螺纹尺寸的直径。
大径：外螺纹的顶径、螺纹的底径。
小径：外螺纹的底径、螺纹的顶径。
中径：一个假想圆柱或圆锥的直径，该圆柱或圆锥的母线通过牙型上沟槽和凸起宽度相等的地方。
单一中径：牙型上沟槽宽度等于1/2基本螺距的地方。
作用中径：在规定的旋合长度，恰好包容实际螺纹的一个假想螺纹的中径，这个假想螺纹具有理想的螺距、螺纹半角、及牙型高度，并在牙顶和牙底留有间隙，不与实际螺纹大、小径发生干涉。
牙型角：在螺纹牙型上，两相邻牙侧间的夹角。
螺距：相邻两牙在中径线上对应两点间的轴向距离。
螺纹精度：由螺纹公差带和旋合长度共同组成的衡量螺纹质量的综合指标。
二、.螺纹概述一般将螺纹分为圆柱螺纹和圆锥螺纹。
（一）圆柱螺纹1. 普通螺纹（又称米制或公制螺纹）螺纹代号M，牙形角60°，基本牙形为平顶。
精度等级：螺纹4~8级，外螺纹3~9级。
2. 美标统一螺纹（又称60°英制螺纹）螺纹代号UNC、UNF、UNEF、UN、UNS，牙形角60°，基本牙形为平顶。
精度等级：螺纹1B~3B，外螺纹1A~3A。
3. 非螺纹密封的管螺纹（又称圆柱管螺纹）螺纹代号G，牙形角55°，基本牙形为圆顶圆底。
精度等级：螺纹标准级和D级，外螺纹A、B级。
4. 梯形螺纹螺纹代号Tr，牙形角30°（美标为29°），基本牙形为平顶平底。
精度等级：7~9级，（美标为2G~6G）。

序号螺纹标注直径（mm）牙距（mm）牙型角（°）备注
备注：
1.公制螺纹标注中的“M”表示公制螺纹，数字为螺纹的公称直径，数字后面的“×”表
示牙距。
2.美制螺纹标注中的数字为螺纹的英寸表示，后面的“-”和数字表示每英寸的牙数，
如“3/4-10UNC”表示3/4英寸的螺纹，每英寸有10个牙。
3.英制螺纹标注中的数字为螺纹的英寸表示，后面的“-”和数字表示每英寸的牙数，
如“PT3/4-14”表示3/4英寸的锥管螺纹，每英寸有14个牙。
4.牙型角为螺纹的牙形夹角，常见的公制螺纹牙型角为60°，英制锥管螺纹牙型角为
55°。
