Purpose and function of the set

The presented wheel security bolt set has been developed as a protective component for Mercedes vehicles from the W176, W204, and W205 series. The design of the bolts allows for installation on both the front and rear axles, enabling consistent protection for the entire set of wheels on the vehicle. The special profile of the working socket requires the use of a dedicated key, which significantly hinders rim removal by unauthorized persons.

Technical construction and fitment

The security bolts are manufactured based on Mercedes factory standards, which translates into a precise fit for the hubs and rims intended for the specified models. The appropriately selected thread working length and the shape of the seating cone ensure proper wheel-to-hub pressure, minimizing the risk of play and unwanted vibrations while driving.

This solution allows for maintaining mounting parameters similar to standard bolts while adding a security feature. As a result, the wheel mounting system remains stable, and the user gains an additional layer of protection without interfering with other suspension or braking system components.

Application on front and rear axles

The placement on the vehicle covers both the front and rear, which allows for the use of a single, consistent security system on all wheels. This solution:

• facilitates vehicle service and maintenance – one type of bolt for both axles,
• ensures an even level of protection for all rims,
• reduces the risk of errors when changing seasonal wheels.

Thanks to this, the set will prove effective both in daily use and in more intensively used vehicles, where the stability of wheel mounting is of key importance for safety.

Performance characteristics and condition

The product is offered as a used item, meaning it comes from disassembly and was previously used in a vehicle. This type of solution allows for maintaining the original manufacturer's specification while reducing costs compared to new sets. For many Mercedes users, this is a reasonable compromise between quality and budget, especially when replacing a single set of security bolts.

Choosing original security bolts from the secondary market is often preferred over replacements of unknown origin, as it maintains compliance with factory mounting parameters and the operating characteristics of the wheel mounting system.

Integration with other components and additional materials

The wheel security bolts work with factory hubs, rims, and suspension components intended for the W176, W204, and W205 models, without requiring additional structural modifications. Proper selection of these types of components is important not only for rim protection but also for vehicle stability at higher speeds and during heavy braking.
