德国原装进口量规、RD螺纹量规
RD是指圆螺纹，是一种按照德国标准的牙型角为30度，螺纹顶和螺纹底都是圆弧状的螺纹规格。可以查阅标准Din405，目前还没有中文版的。
德标DIN405圆齿/圆牙/圆弧RD螺纹塞规/RD螺纹环规/RD量规/通止规
德制圆弧螺纹塞规环规RD105 RD110 RD115 RD120 RD125 德DIN405
螺纹方向分：正牙(右旋)(RH)和反牙(左旋)(LH)
左旋螺纹尺寸代号之后标注“LH”代号。右旋螺纹不标注旋向代号
标记示例
1、规格Rd20 螺距3.175 每英寸牙数8牙 精度7H 右旋圆弧螺纹：Rd20×1/8-7H
2、规格Rd22 螺距3.175 每英寸牙数8牙 精度7H 右旋圆弧螺纹：Rd22×1/8-7H
3、规格Rd16 螺距3.175 每英寸牙数8牙 精度7H 左旋圆弧螺纹：Rd16×1/8-LH-7H
