Purpose and function of the set

Mercedes W164 Wheel Security Bolts Lock Locking Nut has been designed as a factory mounting solution for wheels in W164 series cars. The design of the bolts with a security profile requires the use of a matching key, which effectively prevents unauthorized removal of the rim when parked or in unsecured locations.

The product belongs to the Wheel locks, bolts, nuts and studs category, which means it is a component directly responsible for the stable mounting of the wheel to the hub and for additional protection of the wheel-rim assembly. Thanks to this solution, the user gains a higher level of operational safety while maintaining the vehicle manufacturer's standards.

Construction and technical features

The set includes bolts with a special socket profile that works exclusively with a dedicated key, providing effective protection against the use of standard sockets. This solution is typical for original wheel lock systems used by premium manufacturers, ensuring a precise fit for the rims intended for a given model.

As a wheel mounting component, the bolts are designed to withstand the loads resulting from driving, braking, and maneuvering. The properly selected thread shape and contact surface allow for even tightening of the rim to the hub, which promotes driving stability and reduces the risk of improper wheel seating.

Product condition and service application

The offered set is an aftermarket item, making it an attractive solution for servicing or replacing missing bolts in an existing set. It can be used both for standard wheel changes and for work related to the refurbishment or replacement of rims in Mercedes vehicles.

In workshop practice, such a set is useful for:

• replacing missing security bolts in an existing set,
• restoring the factory locking system after a previous rim replacement,
• upgrading wheel mounting to increase protection against theft.

Benefits of using original wheel locks

Using a dedicated set of security bolts in a Mercedes allows you to maintain the technical consistency of the running gear and adhere to the manufacturer's standards for wheel mounting. The original design of the locks promotes proper force distribution in the rim-hub connection, which is important for the durability of suspension components and driving comfort.

Additionally, using a factory rim protection solution is beneficial from a service perspective – mechanics familiar with Mercedes standards can efficiently perform wheel removal and installation using the appropriate tools, without the risk of damaging the bolt sockets.
