Screw size: M6

The screw size for the rear license plate of an Audi 2005 Quattro is M6. This is a standard metric screw size and can be found at most hardware stores.

When replacing the screws for your rear license plate, it is important to use the correct size to ensure a proper fit and secure attachment. Using screws that are too short or too long can result in loose or improperly positioned plates, which can be a safety hazard.

You may also want to consider the length of the screws, which will depend on the type of frame you are using. If you are not using a frame, an 8mm screw length should be sufficient. For a regular frame, you will need a 12mm screw. If you have a plastic cover frame, a 16mm screw is needed, while an extra-thick cover frame will require a 20mm screw.

It is also recommended to use stainless steel screws to prevent rust and oxidation. Black oxide stainless steel screws can also complement the colour of your license plate or vehicle, providing a stylish and cohesive look.

Some Audi owners have also mentioned that the screws that came with their vehicle from the dealer were prone to rusting, so it may be worth considering an upgrade to ensure the longevity of your license plate screws.

The length of the screws required for your Audi license plate depends on the type of frame you are using. Here are the recommended screw lengths for the different types of frames:

Screw material: stainless steel

When it comes to choosing the right screw material for your Audi 2005 Quattro's rear license plate, stainless steel is an excellent option. Here are some reasons why stainless steel screws are a great choice and some detailed instructions on how to replace your license plate screws:

Benefits of Stainless Steel Screws:

  • Corrosion Resistance: Stainless steel is known for its ability to resist corrosion and rust. This is especially important for license plate screws as they are exposed to the elements. By choosing stainless steel, you won't have to worry about unsightly rust stains on your license plate.
  • Durability: Stainless steel is a strong and durable material that can withstand various environmental conditions. It is less likely to strip or break compared to other screw materials, ensuring that your license plate remains securely attached.
  • Ease of Installation: Stainless steel screws are typically easy to install and remove. They can be fastened using a standard Phillips head or flat head screwdriver, making the process of replacing your license plate screws straightforward.
  • Appearance: Stainless steel screws often have a sleek and modern appearance. They can complement the design of your Audi and enhance the overall look of your vehicle.

Step-by-Step Guide to Replacing License Plate Screws:

  • Gather Tools and Materials: You will need a screwdriver that matches the head type of your current license plate screws (e.g., Phillips or flat head). It is also recommended to wear gloves and safety glasses to protect your hands and eyes during the process.
  • Loosen Old Screws: If the existing screws are difficult to turn, you can apply some penetrating oil to help loosen them. Spray the oil onto the screws and wait a few minutes before attempting to remove them.
  • Remove Old Screws: Using the appropriate screwdriver, turn the screws counterclockwise to remove them. Be careful not to strip or break the screws, as this will make the removal process more challenging. If necessary, you can use tools like pliers or a drill to remove stubborn or damaged screws.
  • Take Out the Old License Plate: Once all the screws have been removed, carefully take out the old license plate and set it aside. Depending on your state's regulations, you may need to return it to the DMV or keep it as a souvenir.
  • Prepare the New License Plate: Clean any dirt or debris from the screw holes on your new license plate. Ensure that the holes align with the screw holes on your vehicle. If you are using a license plate frame, attach it to the license plate before installation.
  • Attach the New License Plate: Place the new license plate in position and insert the new stainless steel screws. Tighten the screws clockwise using your screwdriver until they are snug but not overly tight. Over-tightening can damage the license plate or your vehicle.
  • Test and Adjust: Once the new license plate is secured, gently pull on it to ensure it is firmly attached. Adjust the angle or position of the license plate if needed.

Finding the Correct Screw Size:

It is important to use the correct screw size for your Audi 2005 Quattro's rear license plate. The standard license plate screw size for Audi vehicles is M6-1.0 x 16mm. However, some models may require an extended-length screw if you are using a license plate frame. Always refer to your vehicle's owner's manual or consult a mechanic if you are unsure about the correct screw size.

Screw type: machine pan head, standard, or extended

When it comes to screw types, there are three main options to consider for your Audi's rear license plate: machine pan head, standard, or extended. Here's a detailed guide to help you choose the right type:

Machine Pan Head Screws

Machine pan head screws are a popular choice for securing license plates. They feature a flat head with a recessed Phillips drive, which requires a Phillips-head screwdriver for installation. This type of screw is designed to fit snugly into the recess of the license plate, providing a sleek and low-profile appearance. Machine pan head screws are typically made of stainless steel and are available in various lengths to accommodate different license plate thicknesses.

Standard Screws

Standard screws are the most common type of screw used for license plates. They have a basic design with a round head and a slotted or Phillips drive. These screws are easy to install and provide a secure hold for your license plate. Standard screws are typically made of stainless steel and are available in various lengths. They are a good option if you're looking for an economical and functional solution.

Extended Screws

If you're planning to use a license plate frame or cover, extended screws might be necessary. These screws are longer than standard or machine pan head screws, providing the extra length needed to accommodate the thickness of the frame or cover. Extended screws are typically available in lengths of 16mm or 20mm, depending on the thickness of your license plate frame. Like the other types, extended screws are usually made of stainless steel to resist corrosion.

It's important to note that the screw type you choose should also match the thread size and pitch of your license plate mounting holes. The most common thread size for Audi license plates is M6, but it's always a good idea to check your vehicle's specifications or consult a mechanic to ensure you select the correct screw type and size.

Screw finish: black oxide, black, or silver

When it comes to the finish of screws, you have a few options to choose from, each with its own unique characteristics and benefits. Here are the key details about black oxide, black, and silver finishes for screws, specifically for the rear license plate of your Audi 2005 Quattro:

Black Oxide Finish

Black oxide is a chemical conversion coating that is formed when metal parts are immersed in an alkaline aqueous salt solution at approximately 285 degrees Fahrenheit. This process results in the formation of magnetite on the surface of the metal, giving it a black hue. Black oxide is commonly used on stainless steel, and it offers mild corrosion and abrasion resistance. It is often used as a base for additional protective coatings, such as oil, wax, or lacquer, to enhance corrosion protection. Black oxide screws are available for the rear license plate of various Audi models, including the A5 Quattro, Q3, Q5, and A4 Quattro.

Black Finish

A black finish on screws can be achieved through processes like black oxide coating or electroplating. It provides a sleek and stealthy appearance, complementing the color of your license plate or vehicle. A black finish can also be used to achieve a customized look, making your vehicle stand out on the road. Additionally, some black screws for Audi license plates are made of stainless steel, offering corrosion resistance and durability.

Silver Finish

Silver-colored screws are often made of stainless steel, which is known for its corrosion resistance and durability. This finish provides a neutral and understated look that can seamlessly blend with various vehicle colors. Silver-colored screws made of stainless steel are available for the rear license plate of the Audi 2005 Quattro, as well as other Audi models.

In summary, the choice between black oxide, black, or silver finish for your Audi 2005 Quattro rear license plate screws depends on your specific requirements and preferences. Consider factors such as corrosion resistance, aesthetic appeal, and durability when making your decision.
