The lug nuts on a 2004 Honda Accord are typically M12×1.5 with a 19 mm hex size and a 60-degree conical (tapered) seat.
For most 2003–2007 Accords, these specs apply to factory wheels. If you’ve upgraded to aftermarket rims, verify the lug nut size, seat type, and thread pitch with the new wheel specifications to ensure proper fit and safety.
Core wheel specifications for the 2004 Accord
Understanding the official wheel specifications helps ensure you purchase the correct lug nuts and fasteners for maintenance and wheel changes.
- Bolt pattern: 5 × 114.3 mm (5 bolts on a 4.50 inch circle)
- Center bore: 64.1 mm
- Lug nut size: M12 × 1.5
- Lug nut seat: 60-degree conical (tapered) seat
- Hex size across flats: 19 mm (3/4 inch)

Note: Always torque to specification and re-torque after wheel removal and replacement. If wheels were changed, verify that the lug nuts and seat type match the wheel holes and studs.
Additional considerations
If you’re installing aftermarket wheels or replacing lug nuts, confirm the correct seat type, thread pitch, and seat angle, as some aftermarket products may use 12×1.25 or different seating styles that won’t fit the factory studs or could damage the wheel.

When in doubt, consult the owner’s manual or the wheel manufacturer to confirm compatibility for your specific trim and wheel setup.
