What size socket is a 2016 Honda Accord lug nut?
The lug nuts on a 2016 Honda Accord typically require a 19mm socket (about 3/4 inch).
In practice, this size fits the vast majority of stock wheels for that model, but some aftermarket wheels or adapters can use a different hex size. To avoid damage, verify the exact size for your specific wheel setup by checking the lug nut across flats or the vehicle’s manual.
The following quick checks will help you confirm the correct socket size for your specific wheel configuration.
- Check the owner's manual or the service/parts guide for lug nut specifications that match your exact trim and wheel package.
- Inspect the lug nuts on the wheel for markings indicating the size (some nuts have the size stamped across the flats).
- Measure the nut across the flats with a caliper or ruler if markings are not present, and compare to common sizes (19mm is typical for many Hondas, but some setups use 21mm).
- Test-fit sockets starting with 19mm; if it does not fit snugly or feels loose, try the next standard size (such as 21mm) only if you are sure the wheel requires it.
- Ensure you are using the correct lug nut type and seat (conical, ball, or flat) that matches your wheel, as this can affect the socket size you need.
In most cases for the 2016 Accord, a 19mm socket will fit the lug nuts; always confirm with the manual or wheel manufacturer if you are unsure or using aftermarket wheels.
Torque and safety considerations
Apply the correct torque
When reinstalling, tighten lug nuts to the manufacturer’s torque specification for your model and wheel. For many 2016 Accord configurations, this is typically around 80–95 ft-lb (approximately 110–130 Nm). Use a calibrated torque wrench and re-check the nuts after a short drive to ensure even tightening.
Summary
For a 2016 Honda Accord, the standard lug nut socket size is 19mm. Verify this size for your specific wheels if you have aftermarket components, and always follow the vehicle’s torque specifications to ensure safe lug-nut tension and wheel retention.
