To choose a screw



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.
Relax the requirements. If you need to fix it firmly, you may need to choose a drop-proof screw or a screw with a washer
Other requirements, such as hardening, salt spray test requirements.
