| ①,允许六角面所有边缘和棱角略有圆钝。 ②,六角面与凸缘顶面结合处的圆角半径R不得大于螺钉公称直径的0.15倍。 ③,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。 ④,十字槽插入测量深度由开槽槽深和十字槽槽深两部分组成，由于凹穴槽深的变化是客观存在的，故十字槽插入测量深度可由制造者和用户协商确定。 ⑤,最小槽深比开槽六角头的槽深约小10%。凹穴型凹穴底部以下的槽深度应不小于最小槽深规定值的的1/3。 |
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.
