| ①,螺桿直徑ds應(yīng)不小于2A級(jí)螺紋最小中徑，并不大于公稱（基本）螺紋大徑。 ②,凹穴六角頭允許所有邊緣和棱角略有圓鈍，但支承面圓周直徑不小于最小對邊寬度的90%。 ③,除非用戶有要求，六角頭機(jī)械螺釘不需要開槽。 ④,凹穴型凹穴底部以下的槽深度應(yīng)不小于規(guī)定最小槽深的1/3。 ⑤,除非客戶另有指定，一般應(yīng)提供普通六角頭；普通六角頭和大六角頭可以是凹穴型、切邊成型或完全鐓鍛成型，由制造商指定。 ⑥,頭部對邊寬度和對角寬度應(yīng)在最大部位測量。六角面的斜度（六角面與軸心線之間的夾角）應(yīng)不超過2°或0.004英寸，以較大者為準(zhǔn)，且指定的對邊寬度是大尺寸。 ⑦,由于金屬未完全充滿造成的六角圓鈍應(yīng)盡可能一致。當(dāng)用直徑等于規(guī)定的最小對角寬度的測量量規(guī)測量時(shí)，頭部凸出在量規(guī)外的高度，應(yīng)等于或大于原件列表中的F值。關(guān)于六角頭對角測量詳見強(qiáng)制性附錄II。 ⑧,大六角頭機(jī)械螺釘和墊圈組合件(sems)以及其他要求大支承面的應(yīng)用詳見ASME B18.13。 ⑨,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.
