Most Honda Civics with five-lug wheels use lug nuts sized M12 x 1.5 with a 60-degree conical (acorn) seat, and a 19 mm socket is typically used to tighten them. However, exact size can vary by model year and wheel option, so verify your specific car's specs.
Understanding the standard specs
Many Civics share common lug nut dimensions across generations, especially for factory wheels. The details that matter most are the thread diameter and pitch, the seat shape, and the lug nut socket size you need for removal and installation.
- Thread size: M12 × 1.5 (metric, 12 mm diameter with 1.5 mm thread pitch)
- Seat type: 60-degree conical (acorn) seat, used by most factory Civic wheels
- Socket size: typically 19 mm for lug nuts on many Civics
These specs cover the bulk of modern Civics with standard 5-lug wheels. But some variants may differ.
Variations by year and wheel package
What changes across generations
Honda has updated bolt patterns and lug nut designs over its Civic generations. While most current Civics share M12x1.5 with a 60-degree seat, earlier generations or special editions might use different thread sizes or seat types, especially if fitted with aftermarket wheels or spacers.
Factory vs aftermarket wheels
Aftermarket wheels sometimes require different lug nut types, such as different seat angles (e.g., 45-degree) or different thread specs. If you have aftermarket wheels, always confirm the correct lug nut size with the wheel manufacturer and use the torque specification recommended for the wheel and vehicle.
Installation tips and torque
When installing lug nuts, use a star pattern to ensure even seating, and tighten to the vehicle's specified torque. For most modern Civics, the typical torque range is roughly 80–100 ft-lb (108–135 Nm). Always check your owner's manual or service data for the exact specification for your model year and trim, and re-torque after a short drive to account for settling.
If you're unsure, bring a sample lug nut to a dealership or tire shop to confirm fitment before proceeding.
Summary
In short, the common lug nut size for most Honda Civics with factory wheels is M12 x 1.5 with a 60-degree conical seat, tightened to about 80–100 ft-lb, and typically requiring a 19 mm socket. Always verify against your exact vehicle year, trim, and wheel package, and consult the owner's manual or a professional if in doubt.
What size socket is a Honda Civic lug nut?
Whether you use a lug wrench, torque wrench, impact socket, or regular socket, you'll need the correct size to remove or tighten Honda Civic lug nuts. If the hex size of your wheel nuts is 3/4″, then you would need a 19mm hex socket to fit. Once the head of the lug nut is damaged it will be very difficult to remove it.
What size are the lug nuts on a Honda Civic?
What size are the lug nuts on Honda Civic OEM? The factory lug nuts on most Honda Civics (exclude Type R and 5D) are 12×1.5. This means the lug nuts have a diameter of 12mm and a thread pitch of 1.5mm. Honda uses this sizing for many of their models, including the Civic, Accord, CR-V, and more.
Is a 21mm socket the same as 13/16?
Technically the 13/16 is the smaller and more correct size. Theoretically, both. You can use a 21mm socket on a 13/16 nut. But not vice versa.
Is 7/8 socket the same as 22mm?
A: 22mm = 0.866", which essentialy is a 7/8" socket. A 7/8" socket will work on a 22mm lug nut, but it can feel a little loose. The other way around, a 22mm can work on a 7/8" lug nut, but it can be really snug, which is not bad.
