What size socket is a Ford lug nut?
The standard socket size for most Ford lug nuts is 13/16 inch across flats. However, sizes can vary by model and year, so always verify on the vehicle or in the owner's manual.
Ford’s lineup spans from everyday passenger cars to heavy-duty trucks, and lug nut sizes aren’t universal. This article outlines the typical size and how to confirm the right socket for your specific Ford model.
Common lug nut sizes for Ford vehicles
Here are the sizes you’re most likely to encounter on Ford vehicles.
- 13/16 inch (20 mm) hex lug nuts for the vast majority of Ford passenger cars and light trucks, with a 60-degree conical (tapered) seat. This is the standard socket size you’ll typically use when removing or installing wheels.
If your model isn’t listed here or you’re unsure, verify with the owner’s manual or measure the lug nut across the flats to confirm the correct socket size.
How to verify the size on your Ford
If you’re not sure, follow these steps to confirm the exact lug nut size for your vehicle.
- Inspect an exposed lug nut across the flats with a ruler or calipers to estimate the size.
- Reference the vehicle’s owner’s manual or an online spec sheet for your model/year to confirm lug nut size and seat type.
- Check the wheel or lug nut packaging or a dealer service diagram if you have part numbers handy.
- When in doubt, bring one lug nut or the wheel to a shop to have it measured or replaced with the correct socket.
Always ensure you’re using the correct socket and drive size, and torque the lug nuts to the manufacturer’s specification after wheel installation.
Additional considerations
Lug nut seat types
Most Ford lug nuts use a 60-degree conical (tapered) seat, which pairs with a standard six-point socket. Some wheels or aftermarket setups may use different seat types; mismatch can lead to poor fit or damage. When in doubt, use OEM lug nuts designed for your wheels or consult the wheel manufacturer.
Locking lug nuts and specialty sockets
Ford vehicles equipped with locking lug nuts require the specific key to remove them. If the key is lost, contact a dealer or locksmith. Do not force a standard socket onto a locking nut, as it can damage the nut or wheel.
Safety and maintenance tips
Work on a level surface, use jack stands, and follow Ford’s safety guidelines. Use a torque wrench to re-torque lug nuts after wheel installation and adhere to the recommended torque specs in the owner’s manual.
Summary
For most Ford cars and light trucks, a 13/16 inch (20 mm) socket is the standard lug nut size, typically with a 60-degree conical seat. However, sizes can vary by model and year, especially on heavier-duty trucks or specialty wheels. Always verify the exact size by consulting the owner’s manual or measuring the lug nut flats, and use the correct socket with proper torque when servicing wheels.
