| 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,方槽内壁略带斜度。这个斜度会导致因镀层在槽内的积聚而导致成品紧固件的插入深度测量受限。表中的凹槽插入尺寸适用于成品（镀层）产品。制造商应注意，在生产过程中应为其留出必要的加工余量。 ③,表中的“R”表示正常插入深入。 |
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.
