| ①,機械螺釘的螺紋長度： 1）螺紋規格≤5#: 公稱長度≤3倍公稱直徑的應為滿扣產品，頭下螺紋肩距≤1倍螺距。 公稱長度＞3倍公稱直徑到 1-1/8 in 的，允許頭下肩距最大不超過2倍螺距。 若無其他規定，長螺釘的最小螺紋長度為1 in 。 2）螺紋規格≥6#: 公稱長度≤3倍公稱直徑的應為滿扣產品，頭下螺紋肩距≤1倍螺距。 公稱長度＞3倍公稱直徑到 2 in 的，允許頭下螺紋肩距最大不超過2倍螺距。 若無其他規定，長螺釘最小螺紋長度為 1.5 in 。 ②,螺杆直徑ds應不小于2A級螺紋最小中徑，并不大于公稱（基本）螺紋大徑。 |
長度公差
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.
