①,若以小数规定公称直径，应省略小数前和小数点后第四位的零。
②,螺钉末端钉尖上不允许因螺纹辗压而形成的虚尖，允许略带圆弧或圆钝形末端。
③,小于等于8#的螺钉，螺纹牙顶平面宽度不应超过0.004in，大于8#的应不超过0.006in。
④,正常情况下，当螺钉长度小于等于其公称长度L0时应采用全螺纹，过渡螺纹长度应小于等于Y；若螺钉长度大于其公称长度L0可采用半牙型式，但其螺纹长度应不小于b。

长度公差

　　Tapping screws can be made to any length, but they are generally produced in fractional length increments of 1/16 in. for screws up to 1/2 in. long, 1/8 in. for screws over 1/2 in. through 1-1/2 in. long, 1/4 in. for screws over 1-1/2 in. through 3 in. long, and 1/2 in. for screws over 3 in. long.
