What size socket for lug nuts Honda?
The typical socket size for Honda lug nuts is 19mm hex (about 3/4 inch). Some older or specialty models may require 21mm or, rarely, 17mm, so always verify for your specific vehicle.
Lug nuts come in different seat types and wheel designs, and using the wrong size can damage the nut, wheel, or studs. This guide explains the most common sizes you’re likely to encounter on Honda vehicles and how to confirm the exact size for your model.
Common lug nut sizes you’re likely to encounter
Below are the sizes you’re most likely to see on Honda vehicles in everyday service. The exact size depends on the model year, trim, and wheel configuration.
- 19 mm hex — The most common size for modern Honda models (Civic, Accord, CR-V, HR-V, Pilot, Odyssey, and most others).
- 21 mm hex — Much less common, but can appear with certain wheels or older/less common configurations.
- 17 mm hex — Rare; may occur on aging models or with some aftermarket setups. Verify if you’re unsure.
Knowing the typical sizes helps you prepare, but always confirm the exact size for your car to avoid damage during tire changes.
How to verify the correct size for your Honda
These steps help you determine the precise lug nut size for your specific Honda and wheel setup.
- Check the owner’s manual or service manual for the lug nut size and torque specifications.
- Inspect the lug nuts themselves; sometimes the socket size is stamped on the nut head or end.
- Measure across flats of the lug nut with a caliper or ruler if the size isn’t obvious; compare with common sizes (17, 19, 21 mm).
- If you’re using aftermarket wheels, verify compatibility with the wheel manufacturer or a dealer to ensure the correct socket size.
- When in doubt, bring a wheel or the lug nuts to an auto parts store or service shop to confirm the correct socket size.
Using the exact size is essential to protect lug nuts, studs, and wheels, and it allows proper torque application during reassembly.
Torque and seating considerations
After selecting the right socket, tighten lug nuts to the manufacturer’s specification using a torque wrench, typically around 80–100 ft-lbs (approximately 110–135 Nm) for many Honda models. Tighten in a star pattern and re-check after the vehicle is back on the ground. Avoid relying solely on impact wrenches for final torque; they should only break loose and snug, with a torque wrench completing the job.
Summary
For most Honda vehicles, the standard lug nut socket size is 19mm. Always verify for your specific model by consulting the owner’s manual, checking the nut stamping, or asking a dealer or shop. Use a torque wrench and follow a star pattern to ensure safe, proper tightening and to protect wheels and studs.
