There are many combination screws, there are disc head combination screws, or called round head combination screws. There are also outer hexagonal combination screws. There are two combination screws and three combination screws by type. By material, there are iron and stainless steel. But no matter what. For the length of the combined screws, it is relatively simple.

The length of the general combination screw should be measured with a caliper. The method of measurement is that the combined screw length is not included in the head. But including the pad, flat pad thickness. That is, when the measurement is available, it is the length of the thickness of the pad flat mat.

The minimum size of the standard screw can be to M2 (diameter of thread rod, thread length is unlimited) for example: M2.5 M4 M4 M5 M8 M1 M1M1M1M14 etc. (no length, yes, I'm telling you what the size of the screw is made up of oil: it is the length of the screw rod (excluding the head), (the distance between the thread and the thread) and the diameter of the thread rod.
