What size are the wheel nuts on a Chevy Equinox?
For most Chevy Equinox models, the wheel lug nuts use a standard M12 x 1.5 thread with a 19 mm wrench size. However, variations can occur based on year, trim level, wheel package, or the use of locking lug nuts.
If you’re replacing wheels or lug nuts, it’s important to verify the exact specifications for your specific vehicle. The Equinox line has used similar lug nut fundamentals across many model years, but aftermarket wheels or factory options may introduce differences. Always confirm with the vehicle’s manual, the current hardware, or a Chevy dealership if you’re unsure.
Standard lug nut specifications
The following specifications cover what most Equinox owners will encounter on stock wheels and common aftermarket setups.
- Thread size: M12 x 1.5 (12 mm stud diameter with 1.5 mm thread pitch)
- Seat type: 60-degree conical (acorn) seat
- Hex size (across flats): 19 mm (typically, 3/4 inch)
- Stud diameter: 12 mm
- Nut type: Standard lug nuts are common; some wheels may use locking lug nuts with a key
Understanding these basics helps when shopping for replacements or ensuring compatibility with aftermarket wheels. If you’re using locking lug nuts, you’ll also need the corresponding key to remove or tighten them.
How to confirm lug nut size for your specific Equinox
Steps to verify lug nut size
Follow these steps to confirm the exact lug nut size on your vehicle, especially if you’re replacing wheels or hardware.
- Check the owner's manual or the tire/wheel information label for lug nut specifications
- Inspect the lug nuts currently installed on the vehicle for markings that indicate thread size or seat type
- Measure the hex size across flats with a caliper or standard wrench to verify it is 19 mm
- If your wheels use locking lug nuts, locate the key or contact the dealer for the correct replacement
- When purchasing replacements, confirm compatibility with your wheel type (stock vs. aftermarket) and follow GM’s torque guidance when installing
If you’re unsure after these checks, contact a Chevrolet dealership or a trusted tire shop. Using the wrong lug nuts or an incorrect torque can damage wheels, studs, or the brake components.
Summary
In most Chevy Equinox models, you will find lug nuts that fit 12 mm wheel studs with a 1.5 mm thread pitch and a 19 mm hex size. This standard applies to many stock configurations, but always verify for your specific year, trim, and wheel setup — especially if you have aftermarket wheels or locking lug nuts. When in doubt, consult the owner’s manual or a Chevy service professional to ensure proper fitment and torque.
