What size bolt is a Toyota Avanza stud?
The typical wheel studs on most Toyota Avanza models are M12 x 1.5 in diameter and thread pitch. This size matches the common lug nuts and hub designs used on many recent Toyotas, though exact specifications can vary by year and market.
Because markets, trims and production years can alter hardware, you should confirm the precise size for your vehicle by consulting the owner's manual, checking the dealership parts catalog for your VIN, or measuring the studs directly.
Common size and verification
Below is a concise guide to the typical wheel stud size and how to check that you have the correct parts when replacing studs or lug nuts.
- M12 x 1.5 wheel studs (12 mm diameter, 1.5 mm thread pitch); lug nuts sit on a standard 60-degree conical seat; stud protrusion commonly in the 25–30 mm range, depending on hub design.
To confirm the exact specification for your vehicle, reference the owner's manual or contact a Toyota service center or parts dealer. If you replace studs, ensure the replacement matches diameter, thread pitch, length, and seat type to ensure proper fit and safety.
How to verify and replace safely
If you want to verify the size on your own or replace a worn stud, use these steps to avoid errors.
- Park on a level surface, engage the parking brake, and chock the wheels.
- Remove the wheel to expose a clean hub and studs.
- Measure the stud diameter with calipers and determine the thread pitch with a thread gauge or by comparing to a known reference.
- Compare results with the standard: approximately 12 mm diameter and 1.5 mm pitch for M12 x 1.5 studs.
- If in doubt, consult the Toyota parts catalog or a dealer to confirm before ordering replacements.
Accurate identification helps ensure you use the correct lug nuts and torque values, preventing wheel wobble or mounting issues. Always follow the vehicle’s torque specification for lug nuts as listed in the owner's manual. If you’re unsure, seek professional assistance.
Summary
For most Toyota Avanza models, the wheel stud size is typically M12 x 1.5, but exact specifications can vary by year and market. Verify with the owner’s manual or a dealer, and when replacing studs, ensure proper diameter, pitch, length, and seat type, plus correct torque during installation. This helps ensure safe wheel mounting and reliable performance.
