What size socket is a Toyota wheel nut?
The typical socket size for Toyota wheel nuts is 21 mm (13/16 inch). However, some older models or certain trims may use 19 mm or 22 mm sockets. Always verify with your owner’s manual or by checking the actual lug nuts on your wheel.
Understanding lug nut sizes on Toyota vehicles
lug nut sizes vary by model year, trim level, and wheel configuration. Using the wrong size socket can strip the nut or damage the wheel studs, so it’s important to confirm the correct size before attempting removal or installation. The 21 mm size covers the majority of modern Toyota cars and SUVs, but exceptions do exist.
Common sizes you’re likely to encounter
Before listing the sizes, this paragraph helps set expectations for what you might need in your toolkit when working on Toyotas.
- 21 mm hex (13/16 inch) — by far the most common lug nut size on modern Toyota vehicles, including Camry, Corolla, RAV4, Highlander, and many others.
- 19 mm hex (3/4 inch) — occasionally found on older Toyotas or specific trims; not as widespread but possible.
- 22 mm hex (7/8 inch) — rare, but may appear on some trucks, heavy-duty configurations, or certain aftermarket wheel setups.
Conclusion: For the vast majority of recent Toyotas, a 21 mm socket will fit the lug nuts. If you own an older model, a truck, or have aftermarket wheels, you may encounter 19 mm or 22 mm sizes. Verify before applying force to avoid damage.
How to verify the correct size for your vehicle
Here’s a straightforward checklist to confirm the correct socket size:
- Consult the owner’s manual or service manual for lug nut specifications.
- Inspect the lug nuts on the wheel for size markings or flats; measure across the hex to identify the correct size.
- Test-fit a 21 mm socket first; if it doesn’t fit or feels loose, try a 19 mm or 22 mm socket carefully to avoid rounding the nut.
- When in doubt, visit a dealership or professional mechanic to confirm the exact size for your model and wheel setup.
Using the right size is essential for safe removal and installation, protecting both the lug nuts and wheel studs.
Summary
In practice, most Toyota lug nuts require a 21 mm socket, which covers the bulk of modern models. Some older Toyota vehicles or certain trims may use 19 mm or 22 mm sockets. Always verify the correct size for your specific model and wheel configuration to prevent damage and ensure a proper, safe fit.

What size socket fits a Toyota axle nut?
The most common Toyota axle nut socket size is 39mm, but the size can vary depending on the specific model and year. Some older 4WD Toyota models may use a larger 54mm socket, while other vehicles like certain Tacomas can use a 30mm socket. It's essential to confirm the exact size for your vehicle before purchasing a socket.
Common sizes
- 39mm: This is the most common size for many modern Toyota trucks, SUVs, and cars.
- Specific examples include the 2007-2010 Sequoia, Tundra, and 2008-2010 Land Cruiser.
- 54mm: Used for many older 4WD models such as the 4Runner (1986-1995), Land Cruiser (1975-2007), and Pickup Truck (1979-1995).
- 30mm: Found on certain vehicles like the 2012-2017 Toyota Camry.
- 28mm: Used on some Tacoma models, such as the 1995-2000 4WD versions.
Before you begin
- Confirm your vehicle's specific size: Always verify the correct size for your vehicle's make, model, and year.
- Get the right type: Many Toyota axle nuts use a 12-point socket, but some smaller, older ones may use a 6-point socket.
- Note the length: Axle nuts can be recessed, so a deep-well socket is often necessary.
- Consider impact sockets: Using a high-quality, impact-grade socket is highly recommended for loosening or tightening these very tight nuts, suggests this YouTube video and this YouTube video.
Is 13/16 the same as 21mm?
No, 13/1613 / 1613/16 inch is not the same as $21$mm, but they are very close and often used interchangeably.13/1613 / 1613/16 inch is equal to $20.65$mm, while $21$mm is equal to approximately 0.830.830.83 inches, meaning $21$mm is slightly larger. Because the sizes are so close, a $21$mm socket or wrench will often fit a 13/1613 / 1613/16 inch nut or bolt, and vice versa, though there can be a less-than-perfect fit depending on the manufacturing tolerances of the tools and fasteners.
- 13/1613 / 1613/16 inch = $20.65$mm
- $21$mm = 0.826770.826770.82677 inches, which is slightly larger than 13/1613 / 1613/16 inch
What size socket for Toyota lug nuts?
The socket size for most Toyota lug nuts is 21mm or 13/16". However, the 21mm socket is for the inner lug nut, and a 13/16" socket may not fit if the decorative cap has become damaged or swollen. Newer models, such as the 2023 Tacoma, may require a 22mm socket. To confirm the exact size for your vehicle, check the lug nut's specification or use a tire iron or adjustable wrench to measure the nut.
Recommended socket sizes
- Standard Toyota: Use a 21mm or 13/16" socket for most standard Toyota vehicles.
- Larger Toyota models: Newer models like the 2023 Tacoma may require a 22mm socket.
How to confirm the size
- Check specifications: If possible, find the lug nut's specifications or use the vehicle's manual to determine the correct size.
- Measure: Use a tire iron or an adjustable wrench to measure the lug nut's size.
- Use a tool: Take a lug nut to a hardware store or auto parts store and try it in a socket to find the right fit.
