The size of license plate screws can vary depending on the make and model of the vehicle. However, the most common size for license plate screws is 1/4-14-3/4 inch, where the fraction 1/4 represents the screw’s threaded diameter in inches, the middle number 14 shows the screw’s number of threads, while the last fraction 3/4 is the screw’s length in inches. Here are some examples of license plate screw sizes for specific car models:

• Chevrolet: 10mm in length, but you can opt for a longer 12mm, or shorter 8mm
