attaching a license plate to a car, you need to know what size screws to use. The screws need to be long enough to go through the thickness of the license plate and the bumper, but not so long that they protrude out the back side of the bumper. You also need to make sure that the screws are wide enough so that they can grip into the license plate without stripping out the threads.

Most license plates are made of aluminum, which is a soft metal. This means that you need to be careful when choosing your screw so that you don’t strip out the threads or break off the head of the screw.

There are a few factors to consider when determining what size screw to use for your license plate. The first is the thickness of the metal on the license plate. If the metal is too thin, then the screw could potentially puncture through the other side.

The second factor is the length of the screw. You’ll want to make sure that the screw is long enough to securely hold the license plate in place, but not so long that it protrudes out and becomes a hazard. Lastly, you’ll want to consider what kind of head style would work best with your particular application.

A Phillips head or flat head screws are typically used for this purpose. Now that you know a few things to keep in mind when selecting a screw for your license plate, let’s take a look at some common sizes. For most standard license plates, #8 x 1/2″ screws are typically used. If you have a thicker plate or need a longer screw, then you may opt for a #8 x 3/4″ size instead.

Another popular option is the #10 x 1″ size screws – these will provide a little more holding power than their smaller counterparts. No matter which size or style you choose, be sure to test fit everything before permanently attaching anything! This way you can avoid any potential problems down the road (and save yourself from having to do any re-work).

License Plate Screws

Most cars have license plate screws that hold the plate to the bumper. These screws are usually made of metal, and over time they can rust or become loose. If your license plate falls off, you may be ticketed or fined.

To avoid this, check your license plate screws regularly and tighten them if necessary. You may also want to consider replacing them with stainless steel screws, which are more resistant to rusting.

Are All License Plate Screws the Same Size?

No, all license plate screws are not the same size. In fact, there are four different sizes of license plate screws: 6mm x 20mm, 8mm x 16mm, 10mm x 12mm and 12mm x 12mm. The most common size is the 6mm x 20mm screw, which is used on both the front and rear license plates of most vehicles.

What Size are License Plate Screws Metric?

Most license plate screws are metric, and the most common sizes are M6x1.0 and M5x0.8. These screws are typically between 10-12mm in length, but can be as short as 6mm or as long as 20mm.


When it comes to screws for your license plate, size does matter. The last thing you want is for your plate to fall off because you used the wrong size screw. So, what size screw should you use for your license plate?

The answer depends on the make and model of your car. Most cars these days have metric threads, so you’ll need a metric-sized screw. The most common sizes are M6 and M8.

But before you go and buy a bunch of screws, it’s best to check with your car’s owner’s manual or the dealership to be sure. Once you know the right size screw, all that’s left is choosing the right type. The most common types are Phillips head or flat head screws.

Again, it’s best to consult your car’s owner’s manual or the dealership to see which type is recommended for your car.
