What size is a Toyota license plate bolt?
In most markets, the size of Toyota license plate bolts varies by region. In North America, you’ll typically find 1/4"-14 UNC license plate screws, while many international markets use metric hardware such as M6x1 bolts. Always check your specific model/year or measure the bolts to be certain.
Common sizes by market
These are the sizes you’re most likely to encounter when replacing or inspecting license plate hardware on Toyota vehicles.
North America (US, Canada, Mexico)
- Thread: 1/4"-14 UNC
- Common bolt length: about 1/2" to 3/4" (12.7–19 mm); some installations may use around 1" (25 mm) depending on bumper thickness
- Head type: standard hex or security head options; washers may be included in OEM kits
Note: Some models or OEM accessories use different hardware or captive nuts, so verify against your vehicle’s manual or parts diagram.
International and other markets
- Thread: M6 x 1
- Common bolt length: typically 10–12 mm of threaded portion
- Head type: standard hex or security heads; washers are sometimes used
Notes: In many non-US markets, Toyota uses metric license plate hardware. Check your owner’s manual or the OEM diagrams for your exact model and year to confirm.
How to identify your bolt size
If you don’t have the exact specification handy, use these steps to confirm the correct size for your vehicle.
- Measure the bolt diameter with calipers or a precise ruler to determine whether it is about 6 mm (metric) or 0.25 inches (imperial).
- Check the thread pitch: metric M6x1 has 1 mm pitch; 1/4"-14 UNC has 14 threads per inch.
- Consult your vehicle’s owner’s manual, Toyota parts diagram, or a dealer to confirm the exact hardware for your model/year.
- If needed, bring a sample bolt to an auto parts store to match size and threading.
Using the correct size ensures secure mounting and reduces the risk of stripping or damage to the bumper or plate.
Installation tips
Practical guidance to help you mount or replace license plate hardware safely and cleanly.
- Use washers where required to distribute load and protect the plate and bumper.
- Avoid overtightening; snug is usually sufficient for license plates.
- Apply anti-seize compound on metal-to-metal contact if you expect to remove and reinstall bolts frequently.
Summary: The size of a Toyota license plate bolt depends on market and model. In North America, expect 1/4"-14 UNC screws, typically 1/2" to 3/4" long. In many international markets, metric hardware such as M6x1 with roughly 10–12 mm of thread is common. Always verify via the owner's manual or OEM diagrams, or by measuring the existing bolts.
