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. The points on a 6-point socket apply more force directly to the flats of the lug nut for better grip. Avoid using impact sockets, as they are thicker and may not fit correctly.
It’s also advisable to use a socket with a thin wall if possible. Thinner wall sockets can fit more snugly on the lug nut, reducing the chance of rounding off the edges.
What torque spec are Honda Civic lug nuts?
Honda specifies a torque of 108 Nm for the lug nuts on most Civics. This is the optimal tightening force to keep the wheels securely fastened without over-tightening.
It’s critical to use a properly calibrated torque wrench when tightening lug nuts. An impact wrench or tightening with just a socket can over-torque the lug nuts, stretching the studs. At the other extreme, under-torquing can allow the wheels to gradually loosen over time. Always tighten the lug nuts in a star pattern rather than a circle to ensure even pressure across the wheel.
