How to choose the right screw

To choose a screw, you must first make sure that the screw and the nut can match, that is, the five elements need to be the same: nominal diameter, options, pitch, number of threads, and tooth shape.
Color: The color of the screw is different in different use scenes, and the color needs to be close to the color of the connected object
Screw length: The length is too short, the bite is too little, if it is too long, it may interfere with other parts.
For the choice of screw head type, some will consider anti-disassembly, may use hexagonal or other special shapes, and some will consider appearance.
