In North America, Honda license plates typically use 1/4-14 UNC screws, about 3/4 inch to 1 inch long; in Europe and other markets, the common choice is metric M6 x 1 screws around 12–16 mm long. The exact size can vary by model and year, so it’s best to verify for your specific vehicle.
License plate mounting practices vary by region and model. Some Hondas use self-tapping machine screws, while others rely on bolts or captive nuts built into the bumper or plate frame. Length, head style, and whether washers are needed can also differ depending on plate thickness and mounting hardware.
Common sizes by market
The following sizes cover the most frequently encountered setups for Honda vehicles in major markets. Note that exact dimensions can differ by model, year, and trim, so always confirm with your owner's manual or by inspecting the mounting points on your car.
- United States and Canada: 1/4-14 UNC screws, typically about 3/4" to 1" long (19–25 mm). Common head styles include pan head or button head; may be self-tapping or machine screws depending on the mounting hardware and bumper design.
- Europe and many other markets: Metric M6 x 1 screws, usually 12–16 mm long. Head styles vary (pan, button, or countersunk), and mounting can involve self-tapping screws or bolts into threaded posts or captive nuts.
Regardless of region, using the correct screw size helps prevent plate or bumper damage and ensures the plate stays secure on the road.
How to determine your exact size
Use these steps to identify the precise screws for your specific Honda model and year.
- Inspect the current license plate fasteners on your car to note diameter, thread pitch, and length.
- Check your vehicle’s owner’s manual or a Honda parts catalog for the recommended mounting hardware for your model/year.
- Know your market: US/Canada models typically use 1/4-14 UNC; European models typically use M6 x 1; some exceptions exist based on bumper design and plate frame.
- When purchasing replacements, consider getting a small screw kit that includes both UNC and metric options, plus washers and caps, so you’re prepared for variations.
- If you’re unsure, bring an existing screw to a automotive parts retailer or consult a Honda dealership to confirm the exact size and compatible length.
Confirming the correct size before driving with a new plate helps avoid cross-threading, dash-level vibrations, or plate loss during high-speed travel.
Summary
Honda license plate screw sizes vary by market: 1/4-14 UNC in North America and M6 x 1 in Europe and many other regions, with typical lengths ranging from about 3/4" to 1" (19–25 mm) for US models and 12–16 mm for metric setups. Always verify for your specific model and year by checking the owner's manual or inspecting the mounting points, and consider carrying a small replacement kit to cover common variations.
