License plate screws are bolts that secure the license plate on a vehicle to the frame. They come in various sizes and threads, and they can be either plastic or metal.

But do you know what size are license plate screws? Though there is no unique size and shape of these screws, but something is common among them. Here we will talk everything about the license plate screw size and all related things about it. So, let’s start.

What Size Are License Plate Screws?

There is no universal answer to this question, as the license plate screw size will depend on the make and model of your vehicle and many more things. But commonly, a 10mm- 15 TPI- 1-inch screw is used in most vehicles. 

Besides, you should keep a few measures in mind while selecting the screws. Among them are the diameter, TPI, and finally, length. When all these match your vehicle’s model, the screw fits.

Why Knowing License Plate Screws Size Necessary?

License plate screw size is necessary because they connect the license plate to the frame of the vehicle. This allows law enforcement officials to identify and track vehicles in real-time.

License plates must also be fixed securely so they do not move around during driving, which can lead to collisions and other safety hazards. License plate screws help ensure that these plates stay put while you’re on the road. Without proper-sized license plate screws, it would be difficult to attest the plate to the vehicle, and the result would be worse. For all these reasons, knowing the size of license plate screws are important.

What Type Of Screws Are Best For License Plates?

When choosing screws for license plates, it is important to choose the appropriate type of screw. The most common types of screws used in license plates are flathead screws and hex head screws. 

Flathead screws are less likely to strip the coating off the plate when installed, while hex head bolts provide a tighter fit and resist looseness over time. 

It is also beneficial to choose a screw that matches your driveway’s surface material- if you have concrete or asphalt driveways, then you should use screws designed for those surfaces. 

If your driveway has some dampness or erosion issues, then using stainless steel fasteners may be a better option because they won’t corrode over time.
