The lug nuts on a 2009 Honda Fit use a 12 mm diameter thread with a 1.5 mm pitch (M12x1.5) and require a 19 mm socket for removal and installation. This article explains the exact size, seat type, and practical tips for verifying or replacing them safely.
Key lug nut specifications
Before listing the specs, here are the essential characteristics you’ll encounter on the 2009 Fit.
- Thread size: M12 x 1.5 (12 mm diameter with 1.5 mm thread pitch).
- Seat type: conical (60-degree) seat for correct seating in standard wheels.
- Socket size: 19 mm across flats for installation and removal.
- Bolt pattern: 5 × 100 mm (five lug holes on a 100 mm circle).
These specifications cover the most common configuration for the 2009 Fit and reflect Honda's standard hardware for this model year.
Notes on verification and replacement
If you’re unsure about the hardware on your vehicle—especially if you’ve installed aftermarket wheels—verify against the owner’s manual or consult a Honda dealer to confirm exact specs for your car.
Practical verification steps
Use these steps to confirm lug nut size before you work on the wheels:
- Inspect the existing lug nuts for thread pitch and seat style, which are typically described on the packaging or stamped on the nut.
- Measure the hex size with a socket you already own; for the 2009 Fit it is commonly 19 mm across flats.
- Check the vehicle’s manual or parts catalog if you have aftermarket wheels installed to verify compatibility.
Ensuring you have the correct hardware helps prevent cross-threading, wheel vibration, or damage to studs and wheels.
Summary
For a 2009 Honda Fit, use lug nuts with M12x1.5 thread, a conical 60-degree seat, and a 19 mm wrench size. The wheel uses a 5 × 100 mm bolt pattern. When in doubt, verify with official manuals or a dealer and source OEM-equivalent nuts to ensure proper fit and safety.
