What size socket is the wheel nut on a Ford Transit?
The wheel-nut socket size for most Ford Transit vans is 21 mm across the flats, but some wheels and aftermarket setups use a 22 mm socket. This article explains the typical sizes you’ll encounter and how to confirm the exact size for your specific vehicle, plus safety tips.
Common lug nut sizes you are likely to encounter
Variations by wheel type
The following sizes cover the wheel nuts you’re most likely to see on Ford Transit models, depending on wheel type and regional specifications.
- 21 mm across flats (the most common size for Transit lug nuts).
- 22 mm across flats (seen on some alloy wheels or certain regional variants).
In practice, 21 mm is the default for most Transit wheels, but 22 mm shows up on some configurations. Always verify for your exact wheels and model.
How to determine the exact size for your Transit
To confirm the precise lug nut size for your van, follow these steps:
- Look up the official specification for your exact model year and wheel type in the owner’s manual or Ford service manual.
- Inspect the lug nuts themselves and measure the distance across the flats with a caliper or ruler to identify the correct socket size, or note any markings on the lug nut that indicate the size.
- Try a socket in common sizes (start with 21 mm, then 22 mm) to fit snugly without rounding the lug nut. Do not force a socket if it doesn’t fit.
- If you have aftermarket wheels or cannot determine the size, contact a Ford dealer or qualified mechanic for confirmation and torque specifications.
Confirming the exact size helps prevent stripping the lug nuts and ensures you can safely remove or tighten the wheels when needed.
Safety and torque reminders
Always use the correct socket size and a calibrated torque wrench when installing or removing wheels. Torque specifications vary by model, wheel type, and lug nut design, so follow the official Ford spec for your van and wheel combination.
Summary
The Ford Transit typically uses a 21 mm lug nut socket, with 22 mm appearing on some wheels. The exact size depends on the model year, region, and wheel type, so always verify with the manual or by measuring the lug nuts, and consult a dealer if in doubt. Proper size and torque are essential for safe wheel installation and removal.

What size socket for Ford wheel nuts?
The most common socket size for Ford lug nuts is 13/16" or 21mm, especially for models like the F-150 and Bronco. However, sizes can vary by model year and specific vehicle, with some models like the Bronco Sport using a 19mm (or 3/4") socket. It is best to confirm the exact size for your vehicle, as some older or different models might use a different size.
- 13/16" or 21mm: This is the most common size for many modern Ford vehicles, including the F-150 and Bronco. Some sources suggest 13/16" may be a slightly tighter fit than 21mm, which can help prevent rounding the lug nuts.
- 19mm (or 3/4"): This size is used on certain models, such as the Bronco Sport.
- Verification: It's important to check your vehicle's manual or confirm the size before buying tools, especially since some models use a different size or have swollen lug nuts that may require a special socket.
- Swollen lug nuts: If you have a Ford with swollen lug nuts, a standard socket may not fit. In these cases, a special "flip" socket, which has a slightly larger size, can be used to remove them.

Is a 13/16 socket the same as 21mm?
No, a 13/16 inch socket is not exactly the same as a 21mm socket, but they are very close and often considered interchangeable, as 13/16 inch is approximately $20.65$mm. Because of the small difference, one size may fit a nut or bolt more snugly than the other depending on manufacturing tolerances. The 13/16" socket often provides a tighter fit on many $21$mm lug nuts.
- 13/16" conversion: 13/1613 / 1613/16 inch is equal to approximately 20.6520.6520.65 mm.
- 21mm conversion: 212121 mm is equal to approximately 13/1613 / 1613/16 inch, or 0.8270.8270.827 inches.
- Practical application: While they are theoretically different, many tools and parts manufacturers list them as equivalent, making them effectively interchangeable in practice.
- Best fit: If you have both a 13/16" and a 21mm socket, it is best to try both to see which one fits the fastener most securely without being too loose or too tight. A tighter fit is generally preferred to avoid rounding the fastener head.
