Purpose and technical function

The mounting bolt is responsible for the mechanical connection between the spare wheel and the holder in the luggage compartment, creating a stable mounting point. Thanks to the appropriately selected length and head shape, the component allows for convenient tightening and loosening, while keeping the wheel in a fixed position relative to the trunk floor. This solution reduces the risk of damage to the upholstery and body components resulting from the wheel shifting while driving.

Benefits of using an original Audi bolt

Using an original component from the Audi range translates into:

• Secure fit to the factory spare wheel holder in the Audi A4 B7, with no modifications required.
• Consistency with the trunk design, which facilitates the assembly and disassembly of the wheel in service and emergency conditions.
• Maintaining compliance with the manufacturer's factory solutions, which is important when caring for the technical condition and value of the vehicle.

The element from this group is particularly useful when the existing bolt has been damaged, corroded, or lost, and the user wants to restore the full functionality of the spare wheel mounting system.

Condition of the component and practical application

The offered bolt comes from disassembly and is in used condition, which allows for an economical replacement while maintaining the manufacturer's original specifications. This type of part will work well both as a direct replacement for a damaged component and as a spare for a workshop specializing in servicing Audi models. Installation involves mechanically screwing the bolt into the existing holder, without the need to interfere with the body structure.

Selection support and additional information

When selecting a mounting bolt, it is worth paying attention to the compatibility with a specific vehicle model and the fact that the part has a dedicated OEM number and interchangeable numbers, which facilitates compatibility verification in service catalogs. In case of doubt, it is helpful to compare the shape and mounting method with the factory-installed component.
