①,頭部邊緣為倒圓或平的。 ②,小于等于長度L的螺釘,為清根沉頭型。 ③,機(jī)械螺釘?shù)穆菁y長度: 1)螺紋規(guī)格≤5#: 公稱長度≤3倍公稱直徑的應(yīng)為滿扣產(chǎn)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(guī)定,長螺釘?shù)淖钚÷菁y長度為1 in 。 2)螺紋規(guī)格≥6#: 公稱長度≤3倍公稱直徑的應(yīng)為滿扣產(chǎn)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(guī)定,長螺釘?shù)淖钚÷菁y長度為 1.5 in 。 ④,R代表正常插入深度,S代表短(淺)插入深度。 ⑤,方槽內(nèi)壁略帶斜度。這個(gè)斜度會導(dǎo)致因鍍層在槽內(nèi)的積聚而導(dǎo)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(chǎn)品。制造商應(yīng)注意,在生產(chǎn)過程中應(yīng)為其留出必要的加工余量。 |
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.
