公制螺纹用螺距来表示，美英制螺纹用每英寸内的螺纹牙数来表示，这是它们最大的区分，公制螺纹是60度等边牙型，英制螺纹是等5560度。公制螺纹用公制单位，美英制螺纹用英制单位。管螺纹主要用来进展管道的连接，其内外螺纹的协作严密，有直管与锥管两种。公称直径是指所连接的管道直径，明显螺纹大径比公称直径大。1/4，1/2，1/8种别

ISO5408《公制、美制和英制螺纹标准手册》主编：李晓滨，3862023本手册具有以下几个特点：①弥补了国内目前缺少汉语版的英制和美制螺纹标准的急需；②本书是按国内技术职员生疏的螺纹技术体系编写，易于理解及找出英制和美制螺纹与米制螺纹间的差异；③技术内容正确；④螺纹种类齐全，它包含了紧固螺纹、传动螺纹和管螺纹三大类的常用螺纹；⑤附录系统地先容了各种量具与螺纹要素之间的对应关系，提出了螺纹检测体系概念，为国内技术职员快速进步螺纹产品质量供给了捷径；⑥附录还供给了世界螺纹识别表，解决了国外螺纹识别困难题目；⑦本书为国内第一本全面、具体地先容英制、美制和米制螺纹的技术手册。本书是技术职员和工人的必备工具书。今后本书还间续增加量规、刃具、丈量和强度方面的内容，使其真正地成为“中国螺纹第一书”。7/8“-20UNF-2B1/2“-20UNF-2B7/81/220UNF美国同一螺纹UN〔外螺纹牙底半径任选〕系列中的细牙螺纹；2B7/8“-20UNF-2B,7/8“-207/8“-20UNEF-2B.7/8“-20UNEF-2B0.821－0.832；0.8425－0.84820.0057；大径〔最小〕0.875。1/2“-20UNF-2B0.446－0.457；中0.4675－0.47310.0056；大径〔最小〕0.5000。单位为英寸①外径〔大径〕〔小径〕，与外螺纹牙底或内螺纹牙顶相重合的假想圆柱体直径。③中径，母线通过牙型上突出和沟槽两者宽度相等的假想圆柱体直径。④螺距，相邻牙在中径线上对应两点间的轴向间隔。⑤导程，同一螺旋线上相邻牙在中径线上对应两点间的轴向间隔。⑥牙型角，螺纹牙型上相邻两牙侧间的夹角。⑦螺纹升角，中径圆柱上螺旋线的切线与垂直于螺纹轴线的平面之间的夹角。⑧工作高度，两相协作螺纹牙型上相互重合局部在垂直于螺纹轴线方向上的间隔等。螺纹的公称直径除管螺纹以管子内径为公称直径外，其余都以外径为公称直径。螺纹已标准化有米制〔公制〕和英制两种。国际标准承受米制，中国也承受米制。圆柱螺纹中，三角形螺纹自锁性能好。它分粗牙和细牙两种，一般联接多用粗牙螺纹。细牙的螺距小，升角小，自锁性能更好，常用于细小零件薄壁管中，有振动或变载荷的联接，以及微调装置等。管螺纹用于管件严密联接。矩形螺纹效率高，但因不易磨制，且内外螺纹旋合定心较难，故常为梯形螺纹所代替。锯齿形螺纹牙的工作边接近矩形直边，多用于承受单向轴向力。圆锥螺纹的牙型为三角形，主要靠牙的变形来保证螺纹副的严密性，多用于管件。六、我国常用螺纹标准种别标准名称标准号与国际标准的关系一般螺纹一般螺纹根本牙型GB/T192—1981与ISO68等效一般螺纹直径与螺距系列GB/T193—1981与ISO261等效一般螺纹根本尺寸GB/T196—1981与ISO724等效一般螺纹公差与协作GB/T197—1981与ISO965/1等效一般螺纹偏差表GB/T2516—1981与ISO965/3等效商品紧固件的一般螺纹选用系列JB/T7912—1999与ISO262等效商品紧固件的中等精度一般螺纹极限尺寸GB/T914—1988与
