Key Takeaways

• Understanding What Size Screws for Toyota License Plate: Provides essential knowledge

Understanding Toyota License Plate Screw Standards

When it comes to license plate hardware, Toyota follows a fairly standardized approach—but that doesn’t mean all screws are interchangeable. Most Toyota vehicles use metric screws with specific thread pitch and length. The most common specification is M6 x 1.0 x 16mm or 20mm. Let’s break that down.

The “M6” refers to the screw diameter—6 millimeters. This is the standard size for most passenger vehicles, not just Toyotas. The “1.0” is the thread pitch, meaning there’s 1 millimeter between each thread. This ensures a tight, secure fit without cross-threading. Finally, the length—either 16mm or 20mm—determines how deep the screw goes into the mounting bracket.

Why does length matter? Because Toyota’s license plate brackets vary slightly between models and years. Some have deeper threaded holes, while others use spacers or rubber grommets. A 16mm screw might be perfect for a 2015 Camry, but too short for a 2020 RAV4 with a thicker frame. That’s why it’s crucial to measure or consult your owner’s manual before buying.

Another factor is the head type. Most Toyota license plate screws use a hex head (also called a socket head or Allen head), which requires a 5mm or 6mm Allen wrench. However, some older models or aftermarket kits may use Phillips head screws. While Phillips screws are easier to find, they’re more prone to stripping—especially if you’re using a power drill.

Why Metric Screws?

You might wonder why Toyota uses metric screws instead of the imperial sizes common in the U.S. The answer lies in Toyota’s Japanese engineering roots. As a global automaker, Toyota designs vehicles using the metric system to maintain consistency across markets. This means even if your car is assembled in the U.S., the hardware follows metric standards.

This can be confusing for DIYers used to inches and fractions. But once you get the hang of it, metric screws are just as easy to work with. The key is using the right tools—like a metric socket set or Allen wrench—and double-checking the size before installation.

Common Misconceptions

One common mistake is assuming all license plate screws are the same. While many vehicles use M6 screws, the length and thread pitch can vary. For example, some Honda or Ford models might use M6 x 1.0 x 14mm screws, which are too short for most Toyotas. Using the wrong size can lead to a loose plate, rattling, or even damage to the bracket.

Another misconception is that any screw labeled “M6” will work. But thread pitch matters just as much as diameter. A screw with a 1.25mm pitch won’t fit a 1.0mm threaded hole, even if the diameter matches. Always confirm both diameter and pitch when selecting screws.

Exact Screw Sizes by Toyota Model and Year

Now that you understand the basics, let’s look at specific models. While Toyota tends to stick to M6 x 1.0 x 16mm or 20mm screws, there are exceptions. Here’s a breakdown of common models and their recommended screw sizes.

Camry (1997–Present)

The Toyota Camry is one of the brand’s most popular sedans, and its license plate hardware has remained fairly consistent. For models from 1997 to 2023, the standard screw size is M6 x 1.0 x 16mm. These fit both the front and rear plates on most trims, including LE, SE, XLE, and Hybrid versions.

However, some newer Camrys (2021 and later) come with plastic license plate brackets that use integrated clips or rivets. In these cases, you may not need screws at all—just snap the plate into place. Always check your specific model before assuming screws are required.

Corolla (2000–Present)

The Corolla follows a similar pattern. From the early 2000s to the current generation, most models use M6 x 1.0 x 16mm screws. The compact size of the Corolla means the license plate bracket is relatively shallow, so longer screws aren’t necessary.

One exception is the Corolla Hatchback (2019 and later), which may use slightly longer screws (20mm) due to a thicker rear bumper design. If you’re unsure, measure the depth of the threaded hole or consult a parts diagram.

RAV4 (2001–Present)

The RAV4 is a bit different. Early models (2001–2005) used M6 x 1.0 x 16mm screws, but the third-generation RAV4 (2006–2012) introduced a deeper bracket that often requires 20mm screws. This is especially true for the rear plate, which sits flush with a thicker bumper.

Starting in 2013, Toyota redesigned the RAV4 with a more aerodynamic profile. The 2013–2018 models typically use 20mm screws, while the 2019–2023 RAV4 may use either 16mm or 20mm, depending on the trim and whether you have a tow hitch or spare tire mount.

Tacoma (1995–Present)

The Tacoma pickup truck has a more rugged design, and its license plate hardware reflects that. Most Tacomas from 1995 to 2023 use M6 x 1.0 x 20mm screws, especially for the rear plate. The front plate may use 16mm screws, but it’s common to use 20mm for both to ensure a secure fit.

One thing to note: Tacomas often have license plate frames that double as tow hooks or recovery points. These frames can be thicker than standard, so you might need 25mm screws if you’re installing a heavy-duty aftermarket frame.

Highlander (2001–Present)

The Highlander SUV uses M6 x 1.0 x 16mm screws for most models. However, the third-generation Highlander (2014–2023) introduced a redesigned rear bumper that sometimes requires 20mm screws. Again, it depends on the trim and whether you have a trailer hitch or spare tire.

Prius (2001–Present)

The Prius is known for its eco-friendly design, but its license plate hardware is pretty standard. Most Prius models from 2001 to 2023 use M6 x 1.0 x 16mm screws. The exception is the Prius Prime plug-in hybrid, which may use plastic clips on the rear plate due to its unique bumper design.

4Runner (1990–Present)

The 4Runner is a rugged SUV, and its license plate setup reflects that. Most models use M6 x 1.0 x 20mm screws, especially for the rear plate. The front plate may use 16mm screws, but many owners prefer 20mm for added security.

One tip: 4Runners often have license plates mounted on swing-away tire carriers. If you have this setup, you may need longer screws (up to 25mm) or specialized hardware to accommodate the extra thickness.

How to Identify the Right Screws for Your Toyota

Even with this information, you might still be unsure which screws to buy. Here’s a step-by-step guide to help you identify the right size for your Toyota.

Step 1: Check Your Owner’s Manual

Your owner’s manual is the best place to start. While it may not list screw sizes directly, it often includes diagrams of the license plate area and recommended hardware. Look for sections on “exterior maintenance” or “license plate installation.”

Step 2: Measure the Existing Screws

If you still have the original screws, measure them with a caliper or ruler. Check the diameter (should be 6mm), thread pitch (1.0mm), and length (16mm or 20mm). If the screws are rusted or damaged, compare them to a known M6 screw from a hardware store.

Step 3: Inspect the Mounting Bracket

Look at the license plate bracket on your bumper or trunk. Is it metal or plastic? How deep are the threaded holes? If the holes are shallow, you likely need 16mm screws. If they’re deep or have spacers, 20mm may be better.

Step 4: Consider the License Plate Frame

Are you using the OEM frame, or did you install an aftermarket one? Thick frames—like those made of aluminum or carbon fiber—may require longer screws. Measure the total thickness of the plate and frame, then add a few millimeters for clearance.

Step 5: Test Fit Before Tightening

Once you have the screws, test fit them before fully tightening. The screw should go in smoothly without forcing. If it’s too tight, you might have the wrong thread pitch. If it’s too loose, the length or diameter may be off.

Best Materials and Types of Screws for Toyota License Plates

Not all screws are created equal. The material and coating can make a big difference in durability, especially if you live in a rainy or snowy climate.

Stainless Steel Screws

Stainless steel is the gold standard for license plate screws. They resist rust and corrosion, even in harsh conditions. Look for 18-8 or 304 stainless steel, which are common grades used in automotive applications.

Coated or Zinc-Plated Screws

Zinc-plated screws are cheaper but less durable. The coating can wear off over time, leading to rust. If you choose zinc-plated, make sure they’re labeled “rust-resistant” or “weatherproof.”

Black Oxide Screws

Black oxide screws have a sleek, matte finish that looks great on dark-colored cars. They offer moderate corrosion resistance and are a popular choice for custom builds.

Plastic or Nylon Screws

Some modern Toyotas use plastic screws or clips, especially on the rear plate. These are lightweight and won’t rust, but they’re not as strong as metal. Avoid using plastic screws on the front plate, where they’re more exposed to debris.

Anti-Theft Screws

If you’re concerned about license plate theft, consider anti-theft screws. These require a special key or bit to remove, making it harder for thieves to steal your plate. Many kits include both standard and anti-theft screws, so you can choose based on your needs.

Installation Tips and Common Mistakes to Avoid

Installing license plate screws seems simple, but there are a few pitfalls to watch out for.

Use the Right Tools

A 5mm or 6mm Allen wrench is ideal for hex head screws. If you’re using a socket wrench, a 10mm socket often fits M6 screws with a hex head. Avoid using pliers or adjustable wrenches, which can strip the head.

Don’t Over-Tighten

Over-tightening can strip the threads in the bracket or crack the license plate. Tighten just enough to hold the plate securely—usually a quarter-turn past snug is enough.

Use Washers for Extra Security

Adding a small washer between the screw head and the plate can distribute pressure and prevent loosening over time. Flat washers work best for most applications.

Check for Rattling

After installation, tap the plate gently to check for rattling. If it moves, the screws may be too short or the plate may not be seated properly. Add a rubber gasket or longer screws if needed.

Keep Spares Handy

Losing a screw is easy—especially if you’re driving on rough roads. Keep a few extras in your glove box or trunk, along with a small Allen wrench.

Where to Buy Toyota License Plate Screws

You don’t need to go to a dealership to get the right screws. Here are some reliable options.
