What are the regulations for car license plate screws?
2 Answers
Car license plate fixing screws must use M6 specification bolts. The following is an introduction to the relevant knowledge of car license plate installation: 1. Installation conditions: The vehicle should be equipped with front and rear license plate boards (frames) that meet the requirements for license plate installation. 2. Appearance of metal material license plates: The surface of the license plate should be clear, neat, smooth, glossy, evenly colored, and uniformly reflective, with no obvious wrinkles, bubbles, particle impurities, or other defects or damage. 3. Replacement: License plates that are unclear, incomplete, or affect identification need to be replaced at the relevant departments.
I remember when I helped a friend fix his car, I noticed that the screws for the license plate aren't the ordinary type you can just install casually. In China, regulations require the use of anti-theft screws, which are typically made of aluminum and engraved with the vehicle management office's serial number or regional code. These screws can only be tightened in one direction—once installed, they can't be removed with regular tools. This design primarily aims to prevent license plate theft or misuse, reducing traffic violations. During installation, the vehicle management office provides fixed screws as part of the new car registration process, requiring both front and rear plates to be mounted in designated positions. You can't replace them with other types on your own. If the screws become loose or lost accidentally, you must apply for replacements directly at the vehicle management office—using hardware store screws to save trouble isn't allowed. I once saw a car owner replace the screws himself, only to be pulled over by traffic police, fined, and penalized with points—it's really not worth the risk. Before daily driving, just take a quick glance to ensure the license plate screws are secure.
