What size lug nut for Ford Fusion?
Most Ford Fusion models use M12x1.5 lug nuts on a 5x114.3 bolt pattern with a 60-degree conical seat.
Across generations (from the original 2006 model through the late 2010s variants and into newer trims), wheel specs can vary by year, trim, and aftermarket wheels. The exact lug nut size and seat type should be verified against your vehicle’s manual or by inspecting the existing nuts or wheel manufacturer specs.
Understanding bolt patterns and lug nut sizes
The following list outlines the common specifications you’ll encounter when working with Fusion wheels.
- Bolt pattern: 5x114.3 mm (5 lugs, spaced on a 114.3 mm diameter circle)
- Common lug nut thread size: M12x1.5 for many Fusion generations; some wheels or trims may use M14x1.5
- Seat style: typically a 60-degree conical (acorn) seat
- Typical lug nut hex size: usually around 19 mm for M12 nuts or 21 mm for M14 nuts, depending on the nut design
Because wheel choices and model years can differ, it’s important to confirm the exact size for your specific Fusion before purchasing or reinstalling wheels.
How to confirm the exact lug nut size for your Fusion
Use these steps to verify the precise lug nut size for your car, especially if you’ve swapped wheels or are working from memory.
- Check the owner's manual or the Tire and Wheel section for the recommended lug nut size and torque.
- Inspect the existing lug nuts on your wheels for any stamped size or part numbers that you can cross-reference with Ford’s parts catalog.
- Measure the stud diameter with calipers or a ruler to determine whether you have M12 (about 12 mm) or M14 (about 14 mm) threads, and note the pitch (commonly 1.5 for these models).
- Verify wheel specifications if you’re using aftermarket wheels; wheel manufacturers often list compatible lug sizes and seat types.
- For confirmation, contact a Ford dealer with your VIN or provide the exact model year and wheel size to get the OEM lug nut size and torque specification.
Once you know the exact size and seat type, purchase OEM or high-quality aftermarket lug nuts that match the conical seat, thread pitch, and hex size. Always reinstall using the proper torque in a star pattern to ensure even seating and safety.
Torque and safety tips
Typical torque for Ford Fusion lug nuts is around 100 ft-lbs (135 Nm), but always verify your model’s specification in the owner's manual or on the door jamb sticker. Use a calibrated torque wrench, tighten in a star pattern, and re-torque after the wheels have been driven a short distance or after mounting new wheels.
Summary
In short, most Ford Fusion wheels use a 5x114.3 bolt pattern with lug nuts that are commonly M12x1.5 and a 60-degree conical seat, though exact specs can vary by year and wheel choice. Confirm the precise size from official documentation or by inspecting the existing hardware, and follow proper torque procedures to maintain safety and performance.
