What size are the wheel nuts on a 2010 Subaru Impreza?
The wheel lug nuts are M12 x 1.25 threads with a 19mm hex head, fitted to a 5x100 bolt pattern, and are typically torqued to about 80 ft-lb (108 Nm).
In more detail, the 2010 Impreza uses a 5-lug, 100 mm bolt circle. The lug nuts employ M12 x 1.25 threads with a conical (60-degree) seating surface, and the wheel studs are 12 mm in diameter. A 19 mm socket is standard for installation and removal. While these specs cover most 2010 Impreza models, variations can occur with different trims or aftermarket wheels, so always verify numbers in the owner's manual or with the wheel manufacturer.
Key specifications
The following list summarizes the core lug nut specifications you should know when servicing or replacing wheel hardware:
- Bolt pattern: 5x100 mm
- Thread size (lug nut): M12 x 1.25
- Lug nut seating: Conical 60-degree
- Hex size for installation: 19 mm
- Stud size: 12 mm diameter
- Torque specification: approximately 80 ft-lb (108 Nm)
These values cover the typical 2010 Impreza with OEM wheels. If you’re using aftermarket wheels or adapters, double-check compatibility and torque requirements with the wheel manufacturer or your vehicle’s manual to avoid over-tightening or under-tightening.
Installation tips and safety
To ensure the wheel nuts are properly seated and the wheel is securely mounted, follow these practical steps:
- Use a torque wrench set to the vehicle’s specified value (about 80 ft-lb) and avoid relying on impact wrenches for final torque.
- Tighten in a star or crisscross pattern to evenly seat the wheel against the hub.
- Re-torque the nuts after a short drive (typically 50–100 miles or 80–160 km) to account for settling.
- Ensure you’re using the correct lug nuts for OEM wheels; incompatible hardware can cause seating issues or damage.
- Inspect lug nuts and studs for damage or corrosion before reinstalling wheels.
- If you install aftermarket wheels, verify seat type and thread engagement to match the hub and avoid misfit or loosening.
Following these steps helps prevent wheel loosening and ensures safe operation of the vehicle at speed and under load.
Summary
For a 2010 Subaru Impreza, expect M12 x 1.25 lug thread size with a 19mm hex head, on a 5x100 bolt pattern. Typical torque is about 80 ft-lb (108 Nm), though you should confirm exact values in the owner’s manual or with the wheel manufacturer if using aftermarket parts. Always use proper tools, follow a star pattern during tightening, and re-check torque after a short drive.

What size are the lug nuts on a Subaru Impreza?
The Subaru Impreza lug nut size is M12 x 1.25mm, with a conical 60-degree seat. The hex size, which is the size of the socket you'll need, is most commonly 13/16 inch or 21mm, but can also be 19mm depending on the model and year. Always double-check your owner's manual for the exact specifications for your specific vehicle.
Lug nut specifications
- Thread size: M12 x 1.25mm (meaning a 12mm diameter with 1.25 threads per millimeter)
- Seat type: Conical 60-degree tapered seat
- Socket size (hex): Typically 13/16 inch or 21mm, but some models may use 19mm
Important considerations
- Verify the size: While M12 x 1.25mm is standard for most Subaru Imprezas, it's crucial to confirm the correct size for your specific year and model by checking your owner's manual or contacting a dealership.
- Aftermarket wheels: If you are using aftermarket wheels, they may require a different type of lug nut (e.g., acorn, spherical, shank) with a different seat and potentially a different length. It's important to verify the requirements for your specific aftermarket wheel.
- Torque specifications: Ensure you also use the correct torque specification when tightening the lug nuts to prevent damage to the studs or wheels.
What do M12x1.5 lug nuts fit?
Product Summary: Orion Motor Tech M12x1. 5 Lug Nuts,12x1. 5mm Wheel Lug Nuts Compatible with Toyota Camry Corolla Highlander RAV4 Tacoma, Honda Accord CR-V Civic Fit, Ford Escape Focus Fusion and More, Set of 20.
What size socket for Subaru lug nuts?
The correct socket size for most Subaru lug nuts is 19mm (3/4"). While most Subarus use this size, it's crucial to use a high-quality, thin-wall, 6-point socket designed for automotive use to avoid damaging the lug nuts or wheel.
Details to consider
- Standard size: The most common lug nut size is M12x1.25, which requires a 19mm socket.
- Avoid damage: Using an undersized socket can strip the nut, while an oversized one can cause it to slip. A 6-point socket is recommended over a 12-point socket to prevent rounding the corners.
- Specialty sockets: Some aftermarket lug nuts may have special shapes, like spline drives, which require a specific key socket.
- Older models: Some older Subaru models might require a different size, such as a 21mm socket for those with a 14mm lug nut, but this is rare.
- Protect your wheels: If you have alloy wheels, consider using a thin-wall impact socket or a socket with a protective sleeve to prevent scratching the finish.
