What size are Ford wheel nuts?
Understanding the variation in lug nut sizes
Common sizes you’ll encounter
- M12x1.5 lug nuts with a 60-degree conical seat — typical for most modern Ford passenger cars and crossovers (e.g., Focus, Fusion, Escape, Edge, Mustang).
- M14x1.5 lug nuts with a 60-degree conical seat — used on some larger wheels or specific Ford variants that require a thicker nut and longer stud engagement.
- 9/16-18 UNC lug nuts with a conical or other appropriate seat — common on many Ford F-Series trucks and some heavier-duty applications.
Because vehicle configurations change over time and across markets, the exact lug nut size for a given Ford model and year should be confirmed before purchase or installation.
How to confirm the correct lug nut size for your Ford
- Check the owner's manual or the door jamb sticker for wheel lug specs, including thread size and seat type.
- Look at an existing lug nut on your vehicle or the spare tire’s hardware for stamped size information.
- Measure the wheel studs and thread pitch with a caliper or thread gauge, or bring a known-good lug nut to a parts counter.
- Consult a Ford dealer or a qualified mechanic if you’re uncertain, especially when swapping to aftermarket wheels.
In practice, verifying through official documentation or direct measurement helps prevent cross-threading or improper seating that can compromise safety.
Model-family notes
- Ford passenger cars and standard SUVs (Focus, Fusion, Escape, Edge, Mustang, etc.): typically M12x1.5 with a 60-degree conical seat; common wrench sizes range around standard metric sizes.
- Ford trucks and heavier-duty SUVs (F-Series, Expedition, Super Duty): often use 9/16-18 UNC or M14x1.5 configurations depending on the model year and wheel package.
Always refer to the exact year and trim for precise specs, especially when dealing with aftermarket wheels or unique factory configurations.
