These are the standard hardware specs you’re likely to encounter with the Odyssey’s stock wheels.
- Thread size: M12x1.5 (12 mm diameter with 1.5 mm pitch)
- Nut/socket size: 19 mm (hex size for tightening)
- Seat type: conical (60-degree seating)

Verification and compatibility
To be sure you’re using the right fasteners, check the following guidelines.
- Consult the owner’s manual or a dealership for the exact lug nut specification for your trim and wheel option.
- Inspect the existing lug nuts; if they’re OEM, they should match M12x1.5 with a 19 mm socket.
- Note that aftermarket wheels may use different seat types or lug sizes; always verify compatibility with the wheel vendor.
- Use the correct thread engagement and lug nut style for your wheels.
Verifying helps ensure proper seating, even torque distribution and safe driving.
Seat type and compatibility
The 60-degree conical seat is common for Honda wheels and ensures even seating on the wheel holes. If aftermarket lug nuts use a different seat, you may not obtain proper torque or seating.
Care and maintenance
Best practices to keep the lug hardware in good condition and maintain safe wheel attachment.
- Always torque lug nuts to the manufacturer’s specification using a calibrated torque wrench.
- Tighten in a star or criss-cross pattern for five-lug wheels to ensure even seating.
- Recheck torque after driving 50–100 miles to account for settling.
- Inspect lug nuts and studs for damage, corrosion or signs of wear, and replace as needed.
- Keep a set of spare lug nuts and a lug wrench in your vehicle for emergencies.
Routine checks help prevent wheel loosening, vibration and potential wheel detachment.
Summary
For a 2019 Honda Odyssey, the standard lug nuts are M12x1.5 with a 19 mm hex socket, typically 60-degree conical seat. Always verify torque and seat type against the owner’s manual or dealership guidance, especially if your vehicle has non-OEM wheels.
