Key lug nut specifications
Before you buy or replace lug hardware, it's important to know the official measurements and compatibility. The Type R uses a standard five-lug setup, but the securing nuts themselves have specific sizing you must match. The details below summarize the essential measurements you’ll need when sourcing replacements.
- Thread size: M12x1.5 (12 mm diameter, 1.5 mm thread pitch)
- Seat type: 60-degree conical (tapered) seat
- Socket size: 19 mm hex

- Compatibility note: Use lug nuts that match the seat type and thread pitch of your wheels; aftermarket wheels should specify 12x1.5 with a 60-degree conical seat for Honda FK8
With the right nuts, install carefully to ensure proper seating and avoid damage to studs or wheels during tire changes and high-performance driving.
How to verify on your vehicle
To confirm the exact lug hardware on your Civic Type R, check the wheel spec sheet, owner’s manual, or the packaging of any aftermarket wheels you plan to use.
