What size bolts does Subaru use?
Subaru vehicles use a variety of bolt sizes throughout their construction, with the specific sizes depending on the model and year. In general, Subaru primarily utilizes metric bolt sizes, which are commonly found in many modern automobiles.
Common Subaru Bolt Sizes
The most commonly used bolt sizes in Subaru vehicles include:
- M6 (6mm diameter) - These are often used for smaller components, such as trim pieces, wiring harnesses, and some suspension parts.
- M8 (8mm diameter) - A very common bolt size found in Subaru models, used for things like brake calipers, engine mounts, and various other structural components.
- M10 (10mm diameter) - Larger bolts used for major components like the transmission, differential, and some suspension parts.
- M12 (12mm diameter) - The largest commonly used bolt size in Subaru vehicles, found in applications like the wheel lugs and some suspension linkages.
It's important to note that while these are the most prevalent bolt sizes, there may be some variation depending on the specific Subaru model and year. Always refer to the manufacturer's recommendations or service manual when performing any work on your Subaru to ensure you are using the correct bolt sizes.
Importance of Proper Bolt Sizes
Using the correct bolt size is crucial for the safety and integrity of your Subaru. Improper bolt sizes can lead to components becoming loose, which can result in dangerous situations while driving. Additionally, using the wrong bolt size can damage the threaded holes in the vehicle, making it difficult to properly secure components in the future.
When working on your Subaru, always double-check the bolt sizes and ensure you are using the recommended torque specifications to ensure a secure and safe installation.

To determine bolt diameter, measure the distance from the outer thread on one side to the outer thread on the other side. This is called major diameter. Alternatively, you can measure the bolt shank diameter. The shank is known as the body or sometimes, the shoulder.
