* Designation of the 1st column is firstly used, and the one in the 2nd and 3rd can be used if necessary. The 3rd column will not be in use soon.
* Thickness(t=1.6mm) can be 1.5mm for some time. (in this case, m=1.65mm)
* Minimum width of the circular round of stop ring should exceed the thickness of a plate.
* Fitted hole size depends on standard requirements.
* Minimum width of the circular round of stop ring should exceed the thickness of a plate.
