What size are the lug nuts on a 2019 Ford F150?
The lug nuts are standard 9/16-18 inch fasteners with a 60-degree conical seat, typically using a 22 mm (7/8 in) socket, and they’re torqued to about 140 ft-lbs (190 Nm). If your truck uses aftermarket wheels, verify the spec with the wheel manufacturer.
Factory lug nut specifications
The 2019 Ford F-150 uses six lug nuts per wheel. The factory lug nuts feature a 9/16-18 UNC thread size with a 60-degree conical (acorn) seat, which matches OEM wheels and many aftermarket replacements. A 22 mm (roughly 7/8 inch) wrench/socket is commonly used to install or remove these nuts. The official torque specification for these lug nuts is approximately 140 ft-lbs (190 Nm).
- Thread size: 9/16-18 UNC
- Seat type: 60-degree conical (acorn) seat
- Hex size: 22 mm (7/8 in) socket
- Number of lug nuts per wheel: 6
- Torque specification: ~140 ft-lbs (190 Nm)
Note: These specs cover most factory wheels on a 2019 F-150. If you have aftermarket wheels or a different trim that uses a non-standard configuration, verify the exact lug nut size and seat type with the wheel manufacturer or your vehicle’s manual.
Aftermarket wheels and variations
When replacing wheels, lug nut specs can vary. The following possibilities are commonly encountered with aftermarket setups:
- Some aftermarket wheels use metric M14x1.5 threads and common 22 mm hex lug nuts, which can be compatible with many aftermarket kits.
- Different wheel designs may require a different seat angle (some may not be 60-degree), so ensure the nut seat matches the wheel’s hub face.
- Locking lug nuts or wheel-specific nuts may require their own keys or adapters; use the hardware specified for your wheels.
Always confirm the exact lug nut size, seat type, and torque specification with the wheel manufacturer or your Ford dealer before installation.
Torque and maintenance guidelines
Proper torque is essential for safety and wheel retention. Follow these guidelines when servicing lug nuts on a 2019 F-150:
- Use a calibrated torque wrench and tighten to the recommended specification (approximately 140 ft-lbs for factory 9/16-18 lug nuts).
- Do not use anti-seize on lug studs or lug nuts, as it can affect torque readings; instead, clean threads and apply only if explicitly recommended by the manufacturer.
- After wheel installation, re-torque the lug nuts after driving 50–100 miles (80–160 km) to account for settling.
- Check lug nut torque periodically, especially after road trips or off-road use, and keep a regular maintenance schedule.
Following these steps helps ensure wheel security and reduces the risk of loosening or damage during operation.
Summary
For a 2019 Ford F-150, the typical lug nut specification is 9/16-18 UNC with a 60-degree conical seat, a 22 mm hex size, six nuts per wheel, and a torque target of about 140 ft-lbs. Always verify with the wheel manufacturer if you’re using aftermarket wheels, and adhere to torque and maintenance guidelines to maintain safe wheel attachment.

It is always best to consult your owner's manual or a trusted parts supplier to confirm the exact specifications for your vehicle.
What size lug nuts for Ford F-150?
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 for 2019 F150 lug nuts?
The lug nut socket size for a 2019 Ford F-150 is 21mm. The lug nuts use a 14mm x 1.50 thread size and are designed to be removed with a 21mm socket.
- Socket size: 21mm
- Thread size: 14mm x 1.50
- Torque: 150 ft-lbs (204 Nm)
Can I use 7/8 socket for 22mm?
Yes, you can use a 7/8" socket for a 22mm bolt or nut because they are the same size, with a very small difference that is negligible in practice. 22mm is equal to approximately 0.8660.8660.866 inches, and 7/87 / 87/8 inch is equal to 0.8750.8750.875 inches.
- Size conversion: The two sizes are effectively interchangeable, as they are the closest imperial and metric equivalents.
- Fit: A 7/87 / 87/8" socket will fit on a 22mm bolt. It may feel a little loose, but it will still work.
- Impact tools: This combination is commonly used for impact tools, like those for lug nuts, where sockets are often stamped with both sizes.
- Warning: It's important to use a socket with the correct number of points (e.g., 6-point or 12-point) to avoid damaging the bolt or nut, especially on older or rounded-off fasteners.
