The lug nuts on a Honda Fit are typically M12 x 1.5 with a 19 mm wrench across flats for factory wheels. This size covers most US-market Fits from the 2007 introduction through the 2020 model year, but variations can occur with different wheels or markets. Always verify against your manual or current hardware before any work.
Overview of lug nuts on the Honda Fit
Lug nuts keep the wheels attached to the hub, and their size is defined by thread pitch and the tool size needed to tighten or loosen them. For the Honda Fit, the standard factory configuration has used M12 x 1.5 threads and a 19 mm hex head on the lug nuts across generations. Individual vehicles may differ if they ride on aftermarket wheels or have specialized trims, so checking your specific car is prudent.
Common lug nut sizes by generation
The following summary covers the main Honda Fit generations commonly found in markets outside Japan. It helps you identify the typical hardware you’ll encounter when buying lug nuts or a replacement wrench.
- First generation (roughly 2007–2013; models GE/GD): Lug nuts are M12 x 1.5 with a 19 mm hex head; there are four per wheel.
- Second generation (roughly 2014–2020; models GK): Lug nuts are M12 x 1.5 with a 19 mm hex head; there are four per wheel.
In practice, you’ll most often find the 19 mm lug wrench fits the factory lug nuts on a Honda Fit. If the current lug nuts require a different size, do not force a 19 mm socket; consult the owner’s manual or a dealer to confirm the correct spec for your exact vehicle and wheel package.
How to verify the lug nut size for your vehicle
To be certain you have the correct lug nut size for your specific car, verify using multiple sources and checks. Start with the owner’s manual, then inspect the markings on the lug nuts themselves, and compare with the wheel packaging or installation guide.
- Inspect the lug nuts for stamped size (for example, M12 x 1.5) and cross-check the seat type; if the stamp is unclear, use a reliable wheel service manual or dealership guidance to confirm.
- Measure the lug nut across the flats with a caliper or ruler; most factory nuts measure 19 mm across flats (approximately 0.75 inch).
- Confirm the thread pitch and diameter if you plan to use aftermarket wheels or lug nuts by consulting the wheel manufacturer’s specification.
Always use the correct size and tighten to the manufacturer’s recommended torque specification to ensure safe installation and prevent wheel damage.
Notes on aftermarket wheels and market variation
Some markets or aftermarket wheel packages may use different sizes or alternative seat types. If you’re unsure, contact a Honda dealer or a qualified tire/wheel shop with your VIN or wheel part numbers for precise confirmation.
Summary
For most Honda Fit models—spanning the 2007 through 2020 US-market years—the standard lug nuts are M12 x 1.5 with a 19 mm hex. Variations can occur with aftermarket wheels or different regional models, so always verify against your specific vehicle’s documentation or by asking a qualified technician. Confirming the correct size helps ensure safe installation and proper wheel retention.
