2010 Honda Civic Lug Nut Size: What You Need to Know

The lug nuts on a 2010 Honda Civic use an M12 x 1.5 thread with a 19 mm (3/4-inch) hex head and a 60-degree conical seat; the factory torque specification is approximately 80 lb-ft (108 N·m). This standard applies to U.S. models across trims, though aftermarket wheels may require different seat styles or special nuts.

Core Specifications for the 2010 Civic

Below are the key fitment details most owners and tire shops rely on when servicing or replacing wheels and lug nuts on an eighth-generation (2006–2011) Honda Civic.

• Thread size: M12 x 1.5
• Hex size (wrench): 19 mm (≈ 3/4 in)
• Seat type: 60-degree conical (acorn/tapered)
• Wheel studs/lug count: 5 per wheel
• Bolt pattern (for wheel fitment context): 5×114.3 mm
• Torque spec: 80 lb-ft (108 N·m), applied to clean, dry threads

Together, these specifications ensure proper clamping force and compatibility with OEM wheels; deviations may be necessary only when using certain aftermarket wheels that mandate different seat styles or tuner lugs.

Tools You’ll Need

If you plan to swap wheels or replace lug nuts, having the correct tools prevents damage and ensures proper torque.

• 19 mm lug wrench or socket (impact-rated if using an impact gun)
• Torque wrench capable of 80 lb-ft (108 N·m)
• Breaker bar (for loosening stubborn nuts)
• Plastic or thin-wall socket (to avoid marring alloy wheels)

Using the right tools helps you tighten to spec and avoid rounding the hex or scratching wheel finishes.

Installation and Torque Tips

Following a consistent tightening method protects the studs and ensures the wheel seats evenly on the hub.

1. Hand-thread each lug nut to avoid cross-threading the M12 x 1.5 studs.
2. Snug the nuts in a star pattern to center the wheel.
3. Torque each lug to 80 lb-ft (108 N·m) in a star pattern, then re-check.
4. Avoid lubricants or anti-seize on the threads; torque specs assume clean, dry threads.
5. Re-torque after 50–100 miles of driving, especially after wheel service.

This process minimizes the risk of warped brake rotors, uneven clamping, or loosened hardware over time.

Model and Trim Notes

Across 2010 Civic trims (including DX, LX, EX, EX-L, Si, Hybrid, and GX in the U.S.), the lug nut thread and hex size are the same.

• OEM wheels: Use 60-degree conical-seat lug nuts with 19 mm hex.
• Aftermarket wheels: Some require “tuner” lugs (smaller hex) or different seat types; follow the wheel maker’s guidance.
• Wheel locks: If equipped, the lock key usually also fits a 19 mm socket.

Unless your wheels are non-stock, sticking with OEM-style conical-seat lug nuts ensures proper fit and safety.

How to Verify on Your Car

While the above specs fit most 2010 Civics, a quick check eliminates doubt—especially with aftermarket parts.

• Owner’s manual: Confirms torque and general wheel hardware guidance.
• On-car test: A 19 mm socket should fit snugly with minimal play.
• Parts counter: Provide your VIN or wheel brand/model to confirm seat style and thread.
• Thread gauge: Confirms M12 x 1.5 if studs or lugs have been changed.

Verification is especially important if you purchased the vehicle used or it has customized wheels or studs.

Summary

The 2010 Honda Civic uses M12 x 1.5 lug nuts with a 19 mm (3/4-inch) hex and a 60-degree conical seat. Torque them to 80 lb-ft (108 N·m) on clean, dry threads using a star pattern, and re-check after a short drive—particularly if wheels or tires were recently serviced.

What size socket for 2010 Honda Civic lug nuts?

19mm socket
What size socket and wrench are Honda Civic lug nuts? Since the lug nuts are 12mm in diameter, you’ll need a 19mm socket to remove and install them. A standard 6-point 19mm socket is the proper tool for getting Honda Civic lug nuts off and on. Make sure you’re using a quality 6-point socket, not a 12-point one.

What size socket for Honda lug nuts?

For most Honda vehicles, including the Civic, CR-V, and Accord, the lug nuts typically require a 19mm socket. This is a common size for many Honda models with 12mm x 1.5 lug nuts, according to some auto part sites. 
When selecting a socket, it’s recommended to use a 6-point socket rather than a 12-point, as it provides a better grip on the lug nut and reduces the risk of rounding off the edges, according to a car repair site. A thin-walled socket is also preferable as it can better fit over the lug nut, especially if it’s recessed. 
In summary: A 19mm, 6-point socket is the recommended size for most Honda lug nuts.

Notes: Nut. 12mm x 1.50 Thread Size, 3/4″ Hex.

What size are Honda Civic lug nuts?

Most Honda Civics use M12x1.5 lug nuts. This means the lug nuts have a diameter of 12mm and a thread pitch of 1.5mm. Some older Civic models (like the 1992-1995) might use a 4×100 bolt pattern, while newer models (2006 onwards) generally use a 5×114.3 bolt pattern. 
Here’s a more detailed breakdown:

• M12x1.5: This is the standard lug nut size for most Honda Civics, including the 2001-2025 models. 
• Thread Pitch: The “1.5” in M12x1.5 refers to the thread pitch, which is the distance between the threads on the lug nut and the wheel stud. 
• Diameter: The “12” in M12x1.5 refers to the diameter of the lug nut, which is 12mm. 
• Bolt Pattern: While the thread size remains consistent for most Civics, the bolt pattern can vary. Newer Civics (2006 onwards) generally have a 5×114.3 bolt pattern, while older models may have a 4×100 pattern. 
• Exceptions: Civic Type R models (like the FK8 and FL5) may use a different size, such as M14x1.5. 

To be absolutely sure, it’s always best to:

1. 1. Consult your owner’s manual: This will have the specific lug nut size and torque specifications for your exact model year. 
2. 2. Check the existing lug nuts: You can visually inspect them or use a lug nut size chart to identify the correct size. 
3. 3. Consult a professional: If you’re unsure, it’s always a good idea to consult with a mechanic or tire shop.
