Do all cars use the same license plate screws?
No. There is no universal standard for license plate screws; the hardware varies by country, vehicle design, and mounting method.
Across regions and brands you'll encounter a range of thread pitches, screw sizes, and mounting styles—from simple two-screw setups to rivet-based systems or clip-in plates. This article explains why there isn't a single standard and what to expect depending on where you drive.
North America: Two-screw standard, with variations
Most cars in the United States and Canada secure the plate with two screws or bolts at the plate’s top or bottom edge. The most common hardware is a 6-32 machine screw in lengths typically around 1/2 inch to 3/4 inch; head styles include pan or round heads. Some models use self-tapping screws if there is no pre-threaded hole in the bumper or plate mount.
- Typical fastener type: 6-32 machine screws are common; alternatives include self-tapping screws when no pre-threaded hole exists.
- Security option: Anti-theft or tamper-resistant screws (with a pin in the head) are available and used by some dealers or owners.
- Mounting hardware variations: Some cars use captive nuts or studs rather than visible screws, and many license plate frames come with their own mounting hardware.
When removing or replacing screws in North America, ensure you don’t strip the threads and choose a length that clears the bumper or underlying structure without bottoming out.
Europe and the UK: Metric screws predominate
In Europe, including the UK, license plates are commonly mounted with metric fasteners. The two-screw approach is typical, using screws that thread into pre-installed anchors or into the bumper’s metal structure. The standard thread is usually M6 with a pitch of 1 mm, with lengths around 12–25 mm depending on plate thickness and mounting hardware. Heads can be hex, button, or dome, and many installations rely on a plate holder or frame that hides the screws.
- Typical fastener type: Metric M6 screws are common; some vehicles use bolts with captive nuts.
- Alternative methods: Some cars use plastic rivet-like fasteners or replaceable studs behind the plate.
- Security variants: Anti-tamper screws exist but are less common in everyday European models than in some North American markets.
As with North America, check the vehicle’s manual or OEM mounting hardware for exact sizes and required lengths to avoid damaging the bumper or plate.
Other regions and special cases
Beyond the main markets, you’ll see a mix of hardware. Some vehicles in Asia-Pacific use metric M6 or 8 mm bolts, while others follow regional practices that resemble either North American or European standards. The mounting method can also depend on whether the vehicle uses a built-in plate holder, an aftermarket frame, or a cover that hides the screws.
- Regional variation: Different countries may favor different thread pitches or mounting hardware, so always verify before ordering parts.
- Aftermarket considerations: Plate frames and accessories can introduce additional screws or spacers that change the needed length or diameter.
When in doubt, measure the hole diameter and thread pitch or consult the owner’s manual or a dealer to ensure you select the correct screws without causing damage.
Practical guidance
To replace or upgrade license plate fasteners, bring a sample of the old hardware or measure the hole diameter, thread pitch, and plate thickness; choose the correct metric or imperial screws; consider anti-theft options if you’re concerned about theft; and, if uncertain, seek help from a dealer or body shop to ensure proper fit and legal compliance.
Summary
There is no universal standard for license plate screws. Sizes, pitches, and mounting methods vary by region, vehicle design, and aftermarket accessories. Always use hardware that matches your car’s factory specifications or consult a professional to ensure secure, legal mounting of your license plate.
Do all cars take the same license plate screws?
License plate screws for cars with metal retainers must be a specific size and type to avoid damaging the metal retainer. Threaded holes. Vehicles with threaded metal holes use a specific type of screw.
What type of screws do you need for your license plate?
These screws are an important license plate accessory for auto dealers and private vehicle owners alike. The Hex Head Screws and Pan Head Screws are both #14 1/4 in. x 3/4 in. which is the most universally compatible size and will work with more with most American-Made vehicles like Ford, Chevrolet, Dodge, etc.
What size screw for license plate Honda?
The standard Honda license plate screw size is M6-1.0 (6mm diameter). Common lengths are M6-1.0 x 16mm and M6-1.0 x 20mm. The specific screw size and length may vary depending on the model and year of the Honda, so checking the existing screws or consulting the owner's manual is recommended.
Screw size and length
- Standard thread size: M6-1.0, which is a metric machine screw with a 6mm diameter and a 1.0mm pitch.
- Common lengths:
- 16mm: Used for mounting license plates without a frame or for models that require a shorter screw.
- 20mm: Suitable for mounting with a license plate frame.
Important considerations
- Check existing screws: The most reliable method is to remove one of the existing license plate screws and measure its diameter, thread pitch, and length.
- Confirm with owner's manual: Your Honda's owner's manual or a genuine parts website can provide the specific part number and dimensions for your vehicle.
- Types of screws: While M6-1.0 is the standard for the threaded insert, some older vehicles might use different sizes, such as a #14 screw.
- Replacement hardware: Replacement screws are widely available in various materials and finishes, such as stainless steel and black oxide, to prevent corrosion and match your vehicle's aesthetic.
What screws are typically used for license plates?
MAXIMUM COMPATIBILITY: Our license plate fasteners are the standard size of 1/4" diameter x 3/4” long self tapping screws that will fit most vehicles that use nylon/plastic screw retainers.
