| ①,螺杆直径ds应不小于2A级螺纹最小中径，并不大于公称（基本）螺纹大径。 ②,机械螺钉的螺纹长度： 1）螺纹规格≤5#: 公称长度≤3倍公称直径的应为满扣产品，头下螺纹肩距≤1倍螺距。 公称长度＞3倍公称直径到 1-1/8 in 的，允许头下肩距最大不超过2倍螺距。 若无其他规定，长螺钉的最小螺纹长度为1 in 。 2）螺纹规格≥6#: 公称长度≤3倍公称直径的应为满扣产品，头下螺纹肩距≤1倍螺距。 公称长度＞3倍公称直径到 2 in 的，允许头下螺纹肩距最大不超过2倍螺距。 若无其他规定，长螺钉最小螺纹长度为 1.5 in 。 |
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.
