美制螺纹的表示方法
美标螺纹表示方法学习
在美标中一般螺纹是这样标注
0.25 – 20 UNF – 2 A 以前又为 1/4 – 20 UNF –2A
① ② ③ ④
①--公称直径(现在多以小数表示基本大径,单位:inch)
②--每英寸牙数(即螺距)
③--螺纹系列代号
④--螺纹等级代号
注:
①的数值小于1/4in的小直径系列为公称直径代号,不是公称直径的英寸值,用0,1,2,3,4,5,6,8,10,12 十个号码,来表示。
代号为0,1,2,3,4,5,6,8,10,12 的螺纹大径(in)分别为:
0.060,0.073,0.086,0.099,0.112,0.125,0.138,0.164,0.190,0.216; 粗牙螺纹每英寸牙数分别为:
—,64,56,48,40,40,32,32,24,24;
细牙螺纹每英寸牙数分别为:
80,72,64,56,48,44,40,36,32,28。
