| ①,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 。 ②,除非用户有要求，六角头凸缘螺钉不需要开槽。 ③,六角面与凸缘顶面结合处的圆角半径R应不大于螺钉公称直径的0.15倍。 ④,可选择凹穴型式。 ⑤,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。 ⑥,凹穴型凹穴底部以下的槽深应不小于规定最小槽深的1/3。 ⑦,六角头表面允许所有的边缘和棱角略有圆钝。 ⑧,对边距离和对角距离应在最大部位测量。六角面的斜度（六角面与轴心线之间的夹角）应不超过2°或0.004英寸，以较大者为准，该面应是对边宽度数值较大的平面。 ⑨,由于金属未完全填满而造成的六角圆钝应尽可能一致。当用直径等于规定的最小对角距离的测量量规测量时，头部凸出在量规外的高度，应等于或大于原件表格中的F值。六角头对角测量的相关描述详见强制性附录II。 |
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.
