There are regulations for car license plate screws. The fixing screws for car license plates are required to use M6 specification bolts. According to the "Motor Vehicle Safety Technical Inspection Items and Methods," during the registration inspection, the license plate and its installation must also meet the following requirements: 1. The vehicle should be equipped with front and rear license plate boards (frames) that meet the installation requirements for license plates, but motorcycles only need to have a rear license plate board (frame) that meets the installation requirements. The front license plate board (frame) should be located in the middle or right side of the front (according to the direction of the vehicle's movement), and the rear license plate board (frame) should be located in the middle or left side of the rear. 2. The license plate should be directly and securely installed on the vehicle using M6 specification bolts. 3. For vehicles manufactured on or after March 1, 2016, each license plate board (frame) [except for the front license plate board (frame) of three-wheeled vehicles and the rear license plate board (frame) of motorcycles] should have four license plate installation holes to ensure that the license plate can be directly and securely installed on the vehicle using M6 specification bolts.

I've been driving for over 20 years, and the screws on license plates aren't something you can install casually—there are indeed a bunch of regulations. Looking back, people used to make do with ordinary screws, which often led to rusting and loosening. Once, a license plate fell off on the highway and nearly caused an accident, which really convinced me of the importance of proper screw fastening. Nowadays, standards clearly require screws to be rustproof and of the right size—for example, the diameter shouldn't be too thin, and the length must be sufficient to penetrate the vehicle body, ensuring the plate stays secure. I've checked traffic regulations, and in our area, GB standards detail the screw materials and installation methods, which must meet safety requirements. I strongly advise against cutting corners by buying low-quality screws. Instead, get dedicated ones from authorized shops or 4S stores and check the installation—tight and secure is the golden rule, avoiding fines or accidents. Paying attention to these small details in daily life makes safe driving much more assured.

I recently got new license plates and only found out after checking online that the screw regulations are quite strict. The new rules now require screws to be made of anti-corrosion materials, such as stainless steel or galvanized steel, with specific standards for length and diameter. Otherwise, you might get fined if your plate comes loose and gets caught on camera. I noticed that many online platforms selling screws clearly state compliance information, making it easier to choose the right ones and avoid counterfeit products. During installation, just align them properly and tighten with a screwdriver—no need for excessive force. Since regulations update quickly and local rules may have minor differences, it’s best to check the official website or reliable tools for the latest requirements. This ensures your car stays compliant, safe, and hassle-free on the road.

Of course, there are regulations for screws. Unstable license plates can lead to accidents. I've installed them a few times myself: first, choose compliant screws, preferably made of anti-rust material; use standard tools during installation, tighten them properly without tilting; regularly check for rust or looseness. A common issue is the license plate falling off due to rusted screws, which can easily result in fines or rear-end collision risks. It's recommended to check the condition of the screws every six months and replace any damaged ones promptly.
