What size socket is a 2015 Honda Civic lug nut?
The standard lug nuts on a 2015 Honda Civic require a 19 mm socket to remove and install. This metric size is commonly used on the factory wheels and compatible aftermarket replacements.
For context, lug nuts on Civics use a 60-degree conical seat and thread on the studs of size M12 x 1.5. Four lug nuts secure each wheel, and proper tightening is essential for safety and wheel alignment.
Below are the key socket and lug hardware specs you should know when working on the 2015 Civic wheels.
- Socket size: 19 mm hex (approximately 3/4 inch) to fit the factory lug nuts.
- Thread and seat: lug nuts fit M12 x 1.5 studs with a 60-degree conical (acorn) seat.
- Per-wheel hardware: four lug nuts per wheel.
- Torque specification: tighten lug nuts to roughly 80 ft-lb (108 Nm), following a star pattern.
- Note: If you have aftermarket wheels, verify with the wheel manufacturer, as some designs use different seat types or sizes.
To ensure safety, always re-check lug nut torque after driving a short distance and keep a properly calibrated torque wrench in your vehicle maintenance kit.
Additional considerations
While the basic specs apply to most 2015 Civics with stock or compatible wheels, variations can occur with aftermarket components. Always consult the owner's manual or the wheel manufacturer for specifics on seat type, thread, and torque if you’re not using original equipment.
Wheel installation best practices
When replacing a tire, start all lug nuts by hand to avoid cross-threading, then snug them in a crisscross pattern before final torquing with the torque wrench set to the specified value. Re-torque after the vehicle has been driven a short distance to account for settling.
Summary
The lug nuts on a 2015 Honda Civic require a 19 mm socket, and the standard torque is about 80 ft-lb. This is paired with four lug nuts per wheel, M12 x 1.5 thread, and a 60-degree conical seat. Always verify with your wheel and owner's manual, especially if using aftermarket parts.
