What size are Honda lug nuts?
There isn’t a single lug nut size for every Honda model. Most modern Hondas use M12 x 1.5 studs with a 60-degree conical seat and typically a 19mm hex, but exact sizes can vary by model, year, and wheel type.
Understanding lug nut sizing is essential for safe wheel installation and proper torque. This article outlines common sizes, how to identify the correct hardware for your Honda, and steps to verify before you buy or install new lug nuts.
Common lug nut sizes on recent Honda models
The sizes listed below cover most Honda passenger cars produced in the last 15-20 years. Always verify for your exact model and wheel combo.
Seat type and socket size notes
Most Honda wheels use a 60-degree conical (acorn) seat. The majority of OEM lug nuts require a 19mm socket, though some aftermarket wheels may use different seats or hex sizes. Always confirm the seat type on your wheel and check the service manual or wheel manufacturer if you’re unsure.
- Thread size: M12 x 1.5 is standard for most modern Honda passenger cars.
- Seat type: 60-degree conical (common on Honda wheels).
- Hex size: typically 19mm for OEM hardware; some aftermarket wheels or special editions may use 17mm or 21mm sockets—verify for your setup.
- Torque specification: commonly around 80 ft-lb (108 Nm) for many Hondas; always refer to the owner's manual or door jamb sticker for the exact value.
Because Honda models vary, always refer to the owner’s manual or the door jamb sticker for exact lug nut size and torque for your vehicle.
How to verify the correct lug nuts for your Honda
Use these steps if you’re unsure or if you’re working with aftermarket wheels or a different trim level.
- Check the owner’s manual or service manual for precise lug nut size and torque specification.
- Look for a wheel information label on the driver’s door jamb or fuel filler door; it often lists lug nut size and torque.
- Measure the lug nut hex size with a socket gauge or compare to a socket you know is correct; if in doubt, bring an existing lug nut to an auto parts store to match.
- If you have aftermarket wheels, consult the wheel manufacturer or your Honda dealer with your VIN to confirm compatibility.
Following these steps helps ensure you select the correct lug nuts and torque, preventing wheel loosening or damage.
Summary
In short, while most contemporary Honda models use M12 x 1.5 lug studs with a 60-degree conical seat and a typical 19mm hex, exact sizes can vary by model, year, and wheel configuration. Always verify with official manuals or dealer parts information for your exact vehicle, and torque to the specification provided. If unsure, consult a qualified technician to avoid wheel-related safety issues.
