For those who are new to buy a car and are preparing to apply for an iron license plate, you should pay attention when installing the rear license plate of the BMW 5 Series, because the rear license plate holder is very close to the paint surface of the rear cover box, and if you don’t pay attention, the paint on the rear cover box will be painted. The following is a detailed explanation:
The iron license was installed by myself after I mailed it to me. You must pay attention when installing the iron license. The screws equipped with the Guangdong Vehicle Management Office are M6*18. I don’t know how long they are in other areas. 18mm is too long, and they are still iron. The anti-theft buckle is made of stainless steel. See the picture. The gap between the license plate holder behind the BMW and the rear trunk lid is very close. If you don’t add a license plate frame or spring washer screws, you can use the M6*8 specification. If you add it, you can use the M6*10 specification. I added the license plate frame and spring washer and used M6*10 to work. If it is too long, it will stain the back cover of the car. Remember that the license plate screws at the back must be replaced with short ones. If the vehicle management office installs them, you can bring the screws yourself and ask him to replace them. Otherwise, you may encounter an experienced installer who may replace them with short ones. If you encounter a novice installer, you will definitely stain the back cover of the car. They use an electric flashlight to turn them on the iron plate, which has a lot of torque. If the front is fine, it is the back. Buy 10 304 stainless steel screws online for more than 2 yuan and there is free shipping. If you must use the screws from the Vehicle Management Office, one is to use corner grinding to cut them short, and the other is to put a nut on the screws before putting them on. I use the screws and spring washers. After tightening, no matter how the car bumps or vibrates, the screws will never loosen, because the spring washers are added (the main purpose of the spring washers is to prevent the screws and nuts from loosening due to vibration, activities, etc.). After tightening the screws, fasten the anti-theft cover and you’re done.
