What size socket is a Honda Accord?
For a Honda Accord, the most common sockets you’ll need are 19 mm for lug nuts, 17 mm for the engine oil drain plug, and a 5/8-inch (16 mm) spark plug socket. Sizes can vary by generation and engine, so always confirm for your exact model.
Across generations, Accords use a handful of standard sizes for routine maintenance, but wheel designs, engine options, and aftermarket parts can change the exact requirements. This guide covers the typical sizes you’re likely to encounter and how to verify them on your car.
Common socket sizes by task
Here’s a quick reference listing the sizes most likely needed for basic maintenance on a Honda Accord, including wheel removal, oil changes, and spark plug servicing.
- Wheel lug nuts: 19 mm hex — used to remove and reinstall the wheel on most Accord models.
- Engine oil drain plug: 17 mm hex — used when changing the engine oil.
- Spark plugs: typically a 5/8 inch (16 mm) hex — used with a spark plug socket to remove/install plugs. Some engines may use a different hex size; verify the plug you’re servicing.
Sizes above cover the common tasks for many Honda Accord generations, but differences in year, engine, or trim can alter the exact requirement. Always confirm by inspecting the fastener or checking the service manual for your specific car.
How to confirm the exact size for your model
Check the owner's manual or service guide
Consult the manual or official service documentation for your exact year and engine to confirm the recommended socket sizes for all maintenance tasks.
Ask a parts counter or measure
If you’re unsure, staff at a dealership or auto parts store can confirm the correct sizes for your model year. You can also physically inspect the hex size on the fastener or use a caliper/micrometer to measure the nut or plug hex.
Summary
In short, expect 19 mm for lug nuts, 17 mm for the oil drain plug, and a 5/8 inch (16 mm) spark plug socket for most Honda Accord engines. Always verify for your exact build, as sizes can vary by generation and engine type.

What Size Socket and Torque for Honda Lug Nuts? The correct socket size corresponds to the diameter of your Honda's lug nuts. So for the popular 12×1.5 lug nuts, you'll need a 19mm socket.
What size socket for Honda Accord lug nuts?
A 19mm (or 3/4 inch) socket is the correct size for most Honda Accord lug nuts. This is because Honda Accords use lug nuts with an M12 x 1.5 thread, which corresponds to a 19mm hex size.
- Socket size: 19mm or 3/4 inch
- Thread size: M12 x 1.5
- Why it's important: Using the correct socket size prevents damage to the lug nuts and ensures a proper fit.
- For locking lug nuts: If you have a locking lug nut, you will need a special key from the kit to remove it.

Is 7/8 socket the same as 22mm?
No, a 7/8 socket is not exactly the same as a 22mm socket, but they are often used interchangeably because the difference is very small. A 7/8 inch socket is equal to 0.8750.8750.875 inches, while a 22mm socket is equal to approximately 0.8660.8660.866 inches, making the 7/8 socket slightly larger. Using a 7/8 socket on a 22mm fastener may feel a bit loose, and a 22mm socket on a 7/8 fastener may be a bit snug.
Size comparison
- 7/8 inch socket: 0.8750.8750.875 inches
- 22mm socket: 0.8660.8660.866 inches
Interchangeability and potential issues
- Using a 7/8" socket on a 22mm fastener: This may feel slightly loose because the socket is larger than the fastener.
- Using a 22mm socket on a 7/8" fastener: This may be a snug fit, which is generally better than a loose fit, but could be difficult to use.
- Recommendation: For the most precise fit, it's best to use the correct tool for the job. If you have a 22mm fastener, use a 22mm socket. If you have a 7/8 inch fastener, use a 7/8 inch socket.
When to be cautious
- Corroded or worn fasteners: If a fastener is corroded or the chrome cap has swelled, either socket may fit poorly.
- Torque: For high-torque applications, using the correct size socket is important to prevent damage to the tool or the fastener.
