| ①,這些長度及更短長度為頭部底切型。 ②,若以小數規定公稱直徑，應省略小數前和小數點后第四位的零。 ③,表中的“R”表示正常插入深入。 ④,方槽內壁略帶斜度。這個斜度會導致因鍍層在槽內的積聚而導致成品緊固件的插入深度測量受限。表中的凹槽插入尺寸適用于成品（鍍層）產品。制造商應注意，在生產過程中應為其留出必要的加工余量。 ⑤,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，長螺釘的最小螺紋長度為 1.5 in 。 |
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.
