| 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,方槽内壁略带锥度，以保证插入深量规与有镀层螺钉凹槽的配合。为使插入深测量深度适用于有涂镀层的螺钉，制造者在生产（镦头）时，应为其留出必要的加工余量。 ③,表中的“R”表示正常插入深度。“S”表示短（浅）插入深度。 |
长度公差
Machine screws can be made to any length, but they are generally produced in fractional length increments of 1/16 in. for screws up to 5/8 in. long, 1/8 in. for screws over 5/8 in. through 1-1/2 in. long, and 1/4 in. for screws over 1-1/2 in. long.
