The standard lug nuts on a 2012 Honda Fit typically require a 19mm (3/4 inch) socket, and the studs use an M12 x 1.5 thread. This matches the factory wheel configuration for most trims. If you have aftermarket wheels or locking lug nuts, verify with your manual or wheel supplier.
Key specifications to know
Socket size and fastener details
The common hex size for the stock lug nuts on a 2012 Fit is usually 19mm, paired with M12 x 1.5 threads. If your vehicle has aftermarket wheels or locking lug nuts, the size may differ, so always check the wheel or owner’s manual for the exact specification and torque value.
To confirm your exact lug-nut size and installation torque, consider these steps:
- Consult the owner’s manual for wheel lug nut size and the recommended torque specification (typically around 80 ft-lbs / 108 Nm for a 2012 Fit).
- Inspect the lug nuts themselves for any stamped size markings on the nut.
- Measure the lug-nut hex across the flats with a ruler or caliper to identify the size (19mm is common for M12 studs).
- If you have locking lug nuts, locate the key or contact the dealer to obtain the correct key and socket size.
In most cases, the standard 2012 Fit uses a 19mm socket. For aftermarket wheels or locking lug nuts, verify the exact size with the wheel manufacturer or dealer.
Common socket sizes by lug-nut type
General guidelines for hex sizes based on stud and nut configuration help you select the right tool:
- 12 mm (M12) studs with common lug nuts: typically 19 mm hex sockets.
- 14 mm (M14) studs: typically 22 mm hex sockets.
- Locking lug nuts: require the specific lock key; size may vary, so use the provided key to avoid damage.
If you’re unsure, measure the nut across the flats or check the vehicle’s documentation to avoid rounding off the nut or damaging the wheel.
Safety and maintenance tips for changing a wheel
Before attempting to remove or install lug nuts, follow these precautions to ensure a safe and proper job:
- Park on a level surface and engage the parking brake; turn on hazard lights if needed.
- Place wheel chocks on the wheels opposite the tire being changed.
- Loosen the lug nuts slightly before lifting the car to prevent the wheel from rotating.
- Raise the vehicle using the correct jack points and secure with jack stands if available.
- Remove lug nuts, replace the wheel, and hand-tighten nuts in a star pattern.
- Lower the car and torque the lug nuts to the specified value (about 80 ft-lbs / 108 Nm for a 2012 Fit).
- Re-check torque after driving a short distance to ensure they remain tight.
Following these steps reduces the risk of wheel detachment or damage during driving. If you have aftermarket wheels, always verify torque specs with the wheel supplier.
Summary
For a 2012 Honda Fit, the lug nuts typically require a 19mm socket, with an M12 x 1.5 thread, and a torque of around 80 ft-lbs (108 Nm). Confirm exact specifications if your car has aftermarket wheels or locking nuts, and follow standard safety practices when changing a tire. Always consult the owner’s manual or dealership if in doubt.
