How to verify on your vehicle
These steps help you confirm the correct lug nuts and torque for your exact configuration.
- Inspect the existing lug nuts or the wheel hub for size markings or a part number.
- Cross-check with the owner's manual or a Ford service bulletin for your VIN and wheel type.

- Use a torque wrench to verify the lug nuts are tightened to the recommended specification after wheel installation.
Following these checks ensures your wheels stay securely fastened and safe under normal driving conditions.
Notes for aftermarket wheels
Aftermarket wheels may require different lug hardware. Always confirm that the lug nuts match the seat type and thread size of the hub and the wheel manufacturer’s specifications.

What size are the lug nuts on a Ford F150?
Most modern Ford F-150s (2015-2025) use an M14x1.5 lug nut with a 21mm (or 13/16") socket size. Older models, particularly 2004-2014, may use M14x2.0. It's crucial to check your vehicle's owner's manual or the existing lug nuts to confirm the correct size before purchasing replacements, as some models have different specifications.
Modern F-150s (approx. 2015-2025)
- Thread Size: M14x1.5
- Socket Size: 21mm (or 13/16")
- Seat: 60-degree conical seat
- Length: Approximately 1.75" (44.5mm)
Older F-150s (approx. 2004-2014)
- Thread Size: M14x2.0
- Socket Size: Typically 21mm, but it's best to verify
Important considerations
- Verify your specific vehicle: Always confirm the lug nut size with your owner's manual or by measuring the existing nuts, especially if your truck is an HD model or a specific engine variation.
- OEM vs. aftermarket: Some original equipment (OEM) lug nuts are two-piece with a cap that can be damaged by impact wrenches, making the socket size inaccurate. Replacement one-piece lug nuts are often a more durable option.
- Socket fit: Some 21mm sockets may not fit perfectly on all OEM lug nuts due to wear or a slightly different tolerance.
What size socket is a Ford lug nut?
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.
