Purpose and function of security bolts

The offered set of security bolts has been designed specifically for selected Mercedes models from the W176, W204, and W205 series. These components operate at the critical connection point between the hub and the rim, ensuring stable wheel mounting and additional protection against unauthorized removal. Thanks to the dedicated geometry of the mounting socket, the bolts work only with the appropriate key, which reduces the risk of wheel theft.

Mounting range: front and rear axle

The security bolts are suitable for installation on both the front and rear axles, allowing for consistent protection of the entire set of wheels on the vehicle. This solution provides:

• uniform protection for all rims,
• simplified service – one type of security for both axles,
• maintenance of factory wheel mounting parameters.

Placement on the vehicle covering both the front and rear promotes an even distribution of forces at the wheel-to-hub connection, which is important for the durability of suspension components and driving comfort.

Benefits of using original Mercedes wheel locks

Using original security bolts instead of universal solutions allows you to maintain compliance with the manufacturer's factory standards. The most important advantages include:

• precise fit to hubs and rims intended for a given generation of Mercedes models,
• maintenance of the correct tightening torque and contact surface,
• visual consistency with other wheel mounting elements,
• reduction of the risk of damage to hub sockets resulting from the use of improper bolts.

The product comes from disassembly, which allows for an economical restoration of the factory wheel security system while maintaining the original technical specifications.

Application in service practice

Security bolts of this type are particularly useful when:

• replacing rims with other original sets within the W176, W204, W205 models,
• replenishing a missing set of security locks after previous removal,
• restoring the vehicle to a configuration consistent with the manufacturer's factory guidelines.

Proper selection of security bolts for a specific body version and chassis allows you to avoid problems with wheel mounting, loose connections, or uneven pressure of the rim against the hub.
