Most Audi A5s use lug bolts sized M14x1.5 with a 60-degree conical seat on a 5x112 bolt pattern. In practice, this combination is what most wheel setups require, but variations can occur by model year, market, and wheel option. Always verify the exact hardware for your vehicle to ensure a safe fit.
Common lug bolt size for Audi A5
Here's the baseline hardware profile you’re most likely to encounter on modern A5 models.
- Thread size: M14 x 1.5
- Seat type: 60-degree conical (often called a conical or cone seat)
- Bolt pattern: 5 x 112 mm
- Hardware type: lug bolts (not lug nuts) on many Audi models
In short, these specifications cover the majority of Audi A5 wheels. Always confirm for your specific car, as wheel designs and dealer options can introduce exceptions.
How to verify the correct size for your Audi A5
Because wheel hardware can vary with model year, trim, and aftermarket wheels, use the following steps to confirm the exact lug hardware for your car.
- Consult the owner's manual or your dealership's parts catalog for the exact wheel-hardware specification for your VIN.
- Inspect the current hardware: look for markings on the bolt head and measure the thread pitch with a thread gauge or caliper to confirm M14x1.5, and identify the seat type (60-degree cone).
- If in doubt, bring a sample bolt or your wheel/hub to a qualified technician who can verify the correct length and seat type and provide the proper torque specification.
Getting the right size and seat type is essential for safe wheel mounting, proper seat engagement, and accurate wheel alignment and braking performance.
Summary
For most Audi A5 models, the wheel hardware is M14x1.5 with a 60-degree conical seat on a 5x112 bolt pattern. Always verify for your specific vehicle and wheel combination, since there can be year-by-year or market-based variations. When in doubt, rely on official sources (owner’s manual or dealer) to confirm the exact lug bolt size and torque.
