What size socket is a Chevy Equinox lug nut?
For most Chevy Equinox models, a 21 mm hex socket fits the lug nuts. Some older years or certain wheel configurations may use 19 mm, so it’s best to confirm for your specific year and wheel setup.
Common socket sizes you might encounter
These sizes cover the typical range you may see on Chevrolet Equinox models. The actual size depends on the year, trim, and wheel type.
Most models
- 21 mm (13/16 inch) hex: The standard and most widely used size for contemporary Equinox models with stock wheels.
In everyday use, the 21 mm socket is by far the most common choice for Equinox lug nuts.
Exceptions by year
- 19 mm (3/4 inch) hex: Occurs on some older generations or specific aftermarket wheels and trims.
Some older or specialty configurations may require 19 mm; if the 21 mm socket doesn’t seat correctly, try 19 mm while ensuring you don’t force-fit a socket onto a lug nut.
How to confirm the correct size for your vehicle
Use a quick, reliable process to verify the exact socket size for your car to avoid damaging lug nuts or studs.
- Check the owner’s manual or the wheel/tire specification label (often found on the driver’s door jamb or the fuel door). It may list the lug nut size or the recommended tool.
- Inspect the lug nut across the flats with a caliper or a ruler to identify whether it measures near 21 mm or 19 mm.
- If you have a socket set, test-fit sockets starting with 21 mm; if it doesn’t seat cleanly, try 19 mm. Do not force a socket onto a lug nut.
- When in doubt, consult a professional or bring the wheel to a shop to confirm the correct size.
Verifying the exact size prevents cross-threading and ensures safe removal and installation of the wheel.
Torque and installation considerations
Once you’ve identified the correct socket size, follow the proper torque specifications to secure the wheel safely. For most Chevrolet Equinox models, lug nuts are torqued to about 100 ft-lb (135 N·m), but always verify the exact figure for your year and trim in the owner’s manual or factory service information.
Use a crisscross (star) pattern when tightening and recheck torque after driving 50–100 miles to ensure proper seating.
Summary
The typical lug nut socket size for a Chevy Equinox is 21 mm (13/16 inch), with 19 mm appearing on some older or special configurations. Always confirm for your specific year and wheel setup by checking the manual, wheel label, or measuring the lug nut, and torque to the recommended specification for safe installation.

Is a 13/16 socket the same as 21mm?
13/16" or 21mm is a common interchangeable size for wheel bolts / lug nuts and spark plugs on older cars. I prefer to use 13/16" if I can as it fits tighter. 5-sided is also for bolts used on utility or manhole covers. 5 sided is most likely for a water valve or gas valve in a residential setting.
