Specific use, but also need to pay attention to, if tapping M3 screw hole, then drilling time, the hole distance to be about 2.4mm. That is to say, the actual drilling hole spacing = the size of tapping should be multiplied by 0.85, M3--2.4mm, M4--3.1mm, M5--4.2mm, M6--5.1mm, M8--6.8mm
[packing size] about 240*105*10.1mm
