Application and vehicle function

The described wheel bolt set is intended for installation on the front and rear axle, allowing for consistent wheel mounting across the entire vehicle. The bolts are responsible for securely pressing the rim against the hub, maintaining proper chassis geometry, and ensuring stable force transfer during braking and acceleration.

For Mercedes-Benz A-Class W168 and CLK C209 models, using the correct wheel bolts is important for:

• maintaining proper rim seating on the hub,
• reducing the risk of play and vibrations in the chassis,
• preserving predictable vehicle handling while driving.

Compatibility and identification parameters

The set has been prepared for Mercedes vehicles from the A-Class W168 and CLK C209 series, where the hub and rim design requires the use of dedicated bolts with precisely matched parameters. The product features an OEM designation and assigned interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration in the manufacturer's catalogs and service systems.

Thanks to this solution, it is possible to technically match the component to the factory chassis correctly, without the need to use replacements with uncertain parameters.

Set characteristics and product condition

The presented wheel bolt set includes components intended for installation on one axle of the vehicle, with the possibility of use both at the front and rear, in accordance with service requirements. The product is used, meaning it comes from disassembly, and its selection should be preceded by checking compatibility with the currently installed rims and the specific vehicle's specifications.

In practice, such a set is suitable for:

• replacing damaged or worn wheel bolts,
• restoring the factory configuration after previous modifications,
• replacing missing components after suspension or brake service work.

Benefits of using an original Mercedes solution

Choosing a wheel bolt set dedicated to specific Mercedes-Benz models allows for maintaining structural consistency of the chassis. Properly selected thread parameters, working length, and seat shape translate into correct rim tightening and even load distribution.

Using components compliant with factory specifications reduces the risk of problems such as:

• uneven wheel tightening and the formation of play,
• damage to the rim seats or the hub,
• unwanted vibrations transmitted to the steering wheel.
