What size socket for Honda Civic lug nuts?
A 19mm socket is the correct size for most Honda Civics, covering models from roughly 1972 to 2025. Some specific models or aftermarket wheels may use a 17mm or 21mm socket, so it's best to check your owner's manual or confirm with the wheel and lug nut manufacturer before you start.
- Most common size: 19mm for most Honda Civic models.
- Consider other sizes: Some vehicles and aftermarket wheels may use other sizes like 17mm or 21mm, so check before assuming.
- What to use: A 6-point socket is recommended for the best grip to avoid rounding the lug nuts.
- For the best fit: Consider a socket with a thin wall for a snugger fit if you are working with a lot of clearance.
- When in doubt: Always check your owner's manual or your vehicle's specifications to be certain of the correct lug nut size.

Important considerations
- Aftermarket vs. OEM: Some lug nuts are designed for aftermarket wheels, while others are direct replacements for original equipment manufacturer (OEM) wheels. Make sure the lug nuts match the type of wheels you have.
- Thread pitch: The "9/16-18" specifies the size and thread count. The "9/16" refers to the stud diameter, and the "18" is the number of threads per inch. You must match this to your vehicle's studs.
- Seat type: The seat type (e.g., conical, spherical) must match your wheel to ensure proper contact and secure mounting.
- Confirm fitment: Always verify the exact fitment for your specific year, make, and model before purchasing.
