How to Replace License Plate Screws
Replacing license plate screws is simple and easy, especially if you have the know-how. You’ll need a flathead or Phillips screwdriver to unscrew the old ones and screw in their replacements.
Follow these steps when replacing the old screws:
- Start with the rear license plate. Use the right screwdriver and unscrew the two existing screws on the top of the license plate’s edge or the plate frame (if there is any).
- Remove the license plate (and the plate frame) and set them aside. Clean them if necessary.
- Clear all the dirt and debris around the screw holes.
- Place the license plate (and the frame) back to its original position.
- Start to screw the new screws on the plate or the plate frame using the screwdriver. Make sure that you fully secure the plate and the plate frame.
- Now, go to the front of the car and follow the same procedure in unscrewing and screwing the front license plate.

Most cars manufactured in the United States use sheet metal screws and nylon snap-in nuts for their front and rear license plates, except the Chevrolet Corvette. Most carmakers in Europe and Asia use metric machine screws with threaded inserts.
The screws used for the rear license plates are usually not the same as those on the front license plate. More often than not, there is a license plate mounting bracket at the rear, which is attached first to the car before the license plate. When this bracket is set in place, you know the license plate is fully screwed in.
