What size is the wheel spanner on a Ford Focus?
In most Ford Focus models, the wheel spanner (lug wrench) is 17 mm across flats, sized to fit the wheel lug nuts on standard wheels. However, there are exceptions by generation and market, so confirm with your specific vehicle.
The wheel spanner is part of the spare-wheel toolkit stored in the boot. The exact size can vary if your car has aftermarket wheels or a non-standard spare; this article explains how to verify the correct size for your car and what to do if you can't locate the right tool.
How to confirm the lug-wrench size for your Focus
The following steps help you verify the correct wheel spanner size, since the kit can vary by year and market.
- Check the owner's manual: Look for the spare wheel kit section or tool list, which will specify the lug wrench size (in mm or across flats).
- Inspect the toolkit in the boot: The wheel brace or spanner is usually stamped with its size on the tool itself or on a label inside the kit.
- Examine the lug nuts on the wheel: If you can't find the tool, measure the lug nut across flats with a ruler or caliper to determine the appropriate spanner size.
- Ask a dealer or service centre: If you own a Focus from a different market or a unique trim, staff can confirm the correct size from your VIN or production year.
Understanding the correct size helps prevent rounding or stripping the lug nuts during wheel changes and ensures you have the right tool on hand when you need it.
Model-year and generation notes
Focus generations and toolkit variations
The Ford Focus has undergone several generations since its launch. While the core design of the spare-wheel kit remains similar, the lug nut and spanner size can vary between generations or regional specifications. The most commonly reported size by owners and service information is 17 mm across flats for lug nuts, which matches many Ford wheel nuts of standard size. If your car uses different aftermarket wheels or a non-standard spare, the size in your kit may differ.
Always consult the current owner's manual or contact a Ford dealership with your VIN for the exact specification for your vehicle. Using the correct spanner size is essential to avoid damaging the lug nuts or wheel studs during a tire change.
Summary
For the Ford Focus, the wheel spanner is typically 17 mm across flats, but verify for your model year and market. If in doubt, check the owner's manual or toolkit labeling, measure the lug nuts, or ask a dealer. Being sure of the size helps you change a flat safely and quickly.
