m3的底孔应该打多大?
与你所用的丝锥螺距有关,M3一般常用2.5MM的丝锥,其底孔直径则为2.459MM。
m4/m5/m6/m8的底孔应该各打多大的?
与你所用的丝锥螺距有关,M4和M5一般常用3.3MM的丝锥,M6一般常用5MM的丝锥,M8 一般常用7MM的丝锥。其底孔直径分别为3.242MM、4.134MM、5MM和7MM。
m5的螺丝空底孔应该打多大?
内螺纹底孔(d)的计算取决于螺纹外径(D)和螺距(t),通常可用如下公式计算:d=D-(1~1.2)*t。以M5螺孔为例,t=0.8;D=5,内螺纹底孔直径则为4.1~4.2MM。
SUS201材质的M2/M2.5/M3/M4/M5螺栓的拧紧扭矩数值各是多少?
只有材质信息,没有等级信息,下次问的时候请提供等级信息。以下是SUS201材质的M2/M2.5/M3/M4/M5螺栓的拧紧扭矩数值:
- M2:0.3NM
- M2.5:0.6NM
- M3:1.1NM
- M4:2.7NM
- M5:5.5NM
拧紧扭矩通常是破坏扭矩的75%-80%。
