What size thread is a Subaru Crosstrek?
The most common interpretation of "thread size" for the Crosstrek refers to wheel lug hardware. For most recent Crosstrek models, the lug studs use M12 x 1.25 threads, the wheel bolt pattern is 5x100, and lug nuts typically require a 19 mm socket. The hub bore is about 56.1 mm. Variations can occur by year, trim, or aftermarket wheels.
The term "thread size" can apply to several fastener types on a vehicle. This article focuses on the wheel-related threads—the ones most homeowners and technicians encounter when replacing wheels or lug hardware. Other components, such as engine oil drain plugs or transmission plugs, use different sizes depending on the engine and model year.
Wheel lug nuts and studs
The following specifications cover the wheel lug hardware you are most likely to encounter when working with Crosstrek wheels.
- Thread size of lug studs: M12 x 1.25
- Bolt pattern: 5x100 mm
- Lug nut seat type: 60-degree conical (acorn) seat
- Hub bore diameter: approximately 56.1 mm
- Lug nut socket size: 19 mm
- Note: Some variations can occur by model year, trim, or aftermarket wheels; always verify with the vehicle's specifications or VIN.
These wheel-related specs help you select compatible lug nuts and wheels. If your Crosstrek uses aftermarket rims or has a different hub configuration, re-check the exact measurements for that setup.
Other threaded components on the Crosstrek
Engine oil drain plug
Thread size for the engine oil drain plug can vary by engine family and year. Many Subaru engines use a drain plug with a metric thread around M14 x 1.5, but you should verify the exact specification for your specific engine by consulting the owner's manual or service documentation.
Transmission and other drain plugs
Drain plugs for transmission pans or other subsystems on the Crosstrek can also vary by year and transmission type (manual, CVT, etc.). Always refer to the factory service manual or a dealership to confirm the correct thread size before servicing.
Summary: For wheel-related maintenance, the Crosstrek's lug studs typically use M12 x 1.25 threads on a 5x100 bolt pattern, with a 56.1 mm hub bore and a 19 mm lug-nut socket. Other threaded components (oil, transmission, etc.) vary by year and engine; verify exact specifications in the official manuals or with a dealer for your exact vehicle.

What size are the lug nuts on a Subaru Crosstrek?
The lug nuts for a Subaru Crosstrek are M12x1.25mm, which refers to the thread size. The socket size needed to fit these lug nuts is typically 19mm (or 3/43 / 43/4 inch). You should confirm the exact specifications for your model year, especially for the 2024 and newer models which may have a different lug pattern.
- Thread Size: M12x1.25mm
- Socket Size: 19mm or 3/43 / 43/4 inch
- Seat Type: For most factory wheels, they will be a conical seat type.
- Model Year Considerations: The lug pattern is 5x100mm for models from 2013-2023 but is 5x114.3mm for 2024 and newer models. However, the thread size remains M12x1.25mm for all listed model years.
What size wrench for Subaru Crosstrek drain plug?
All plugs have 14mm hex – just one wrench works for all.
What thread pitch are Subaru lug nuts?
Subaru lug nuts have a M12x1.25 thread pitch, meaning they have a 12mm diameter and a 1.25mm thread pitch. This is a key specification to remember when replacing lug nuts or wheels, as it differs from the more common 1.5mm thread pitch used by other Japanese manufacturers, according to arts automotive.

- Diameter: 12mm
- Thread Pitch: 1.25mm
- Commonly Used: This specification applies to most Subaru models, including the Crosstrek, Forester, Impreza, and Legacy, from around 1990-2023.
- Importance: Using the correct thread pitch is crucial to avoid cross-threading and potential damage to the wheel studs or hub assembly. Always check your owner's manual to confirm specifications for your specific vehicle.
