Securing Your E46 Coupe: M5x8 Lock Screws For License Plate

The M5x8 lock screw is a type of screw used to attach license plates to cars. Specifically, the BMW E46 Coupe uses M5x8 screws to secure its license plates to the car. These screws are typically made of stainless steel and are designed to be corrosion-resistant and durable. They are available in different lengths to accommodate different license plate thicknesses and frame configurations. It is important to use the correct length of the screw to ensure a secure fit and prevent damage to the car's body or bumper.

BMW E46 Coupe licence plate screw size

The screw size for the BMW E46 Coupe licence plate is M5x8. These screws have a flat blade top and you will need four per plate.

While the M5x8 screw size is standard for the E46 Coupe, the length of the screw may vary depending on the car. For example, one source states that the M5x12 screws in the back of their touring model were too short for their new license plate frame, so they opted for M5x16 screws instead.

You can purchase these screws from a variety of retailers, including Amazon, BMW Parts, and Turner Motorsport.

It is important to note that some customers have complained about the fit of the screws, with some saying they are too short to support both the license plate and frame. Therefore, it is recommended to check the length of the screws before purchasing to ensure they are the correct size for your car.

BMW E46 Coupe licence plate screw alternatives

If you're looking for alternatives to the standard M5x8 lock screw for your BMW E46 Coupe's licence plate, there are a few options to consider.

Firstly, it's important to note that the length of the screw you choose will depend on whether you're attaching a bare licence plate or one with a frame. The standard M5x8 screw is typically used for a bare licence plate, while a longer screw such as the M5x12 or M5x16 may be needed if you're attaching a frame as well.

When choosing a replacement screw, it's recommended to opt for stainless steel, as this material offers good corrosion resistance. In particular, Type 316 Stainless Steel (also known as "marine grade" stainless steel) is an excellent choice due to its enhanced corrosion resistance compared to Type 304.

• M5x12 or M5x16 stainless steel button-head screws: These longer screws can accommodate both the licence plate and a frame. They have a sleek appearance and are available in Type 316 stainless steel for superior corrosion resistance.
• M5-0.8 x 10mm or M5-0.8 x 8mm stainless steel pan-head screws: These screws offer a secure fit and are available in both standard and black oxide finishes. The black oxide finish adds an extra layer of protection against rust.
• M5-0.8 x 8mm black stainless steel Torx screws: These screws provide a secure attachment and have a unique head design that may deter theft.
• M5-0.8 x 12mm black oxide Phillips machine pan-head screws: These screws are specifically designed for BMW and Tesla vehicles, offering a precise fit. The black oxide finish provides enhanced corrosion resistance.

When replacing your licence plate screws, it's important to consider the length of the screw, the type of head/drive, and the material. Always opt for high-quality stainless steel screws to ensure durability and corrosion resistance.

BMW E46 Coupe licence plate screw length

The BMW E46 Coupe is a stylish car, and you want to ensure that your license plate is securely attached and complements the vehicle's appearance.

The standard license plate screw thread for BMWs is M5, and the length depends on the car. For the E46 Coupe, the rear license plate screw length is typically M5x8 or M5x12, while some owners have mentioned using M5x16 for a more secure fit with a license plate frame.

It's important to note that the screw length required depends on the total thickness of your license plate setup, which includes the license plate itself, any frame or cover, and the screw covers or washers. Using screws that are too short can result in loose plates, while screws that are too long can damage your car's body or bumper.

When choosing screws, opt for stainless steel, which offers better corrosion resistance than other materials. Black-oxide-coated stainless steel screws can also add a stylish touch to your license plate and provide an additional layer of protection against the elements.

Remember to use the correct type of screwdriver for the screw head. Phillips and Hex (Allen) head screws are common, and you can easily find drivers for them.

You can purchase license plate screws from automotive stores, hardware stores, or online retailers. When buying, pay attention to the screw specifications to ensure they fit your E46 Coupe perfectly.

Now you're ready to securely attach your license plate to your BMW E46 Coupe with screws that complement the car's sleek design!

BMW E46 Coupe licence plate screw anti-theft

The BMW E46 is a popular car model that requires specific licence plate screws for a secure and proper installation. To ensure the safety of your licence plate and deter theft, it is essential to use anti-theft screws designed specifically for the BMW E46 Coupe. Here is a comprehensive guide to help you choose and install the right anti-theft screws for your BMW E46 Coupe's licence plate.

Understanding Licence Plate Screws for BMW E46 Coupe:

Firstly, it is important to know the correct screw size for your BMW E46 Coupe. The factory screw size for this model is M5x8, which refers to a metric 5mm screw shaft diameter and an 8mm screw length. When replacing the screws, ensure that you use the correct length to avoid any damage to your vehicle.

Choosing the Right Anti-Theft Screws:

When it comes to anti-theft screws for your BMW E46 Coupe's licence plate, you have several options:

• Security Screws: You can opt for security screws with unique head designs that require specific tools to install and remove, such as spanner, polydrive, or tri-wing drivers. These screws act as a visual deterrent and require special tools that thieves are less likely to carry.
• Hex Head Screws: Hex head screws are a popular choice due to their simplicity and wide availability. They have a hexagonal recess in the head that requires an Allen key for installation and removal. Hex screws are small and elegant, and Allen keys are readily available.
• Torx Screws: Torx screws feature a star-shaped pattern in the head and require a specialised Torx driver. They offer a good balance between security and convenience. However, ensure you remember the specific Torx size and keep the driver bit safe, as there are various Torx types and sizes.
• Other Options: You can also consider anti-theft kits that include tamper-proof screws, screw caps, and covers. Additionally, some kits offer rustproof stainless steel screws, which are ideal for outdoor use and provide long-lasting protection against corrosion.

Installation and Maintenance Tips:

When installing the anti-theft screws for your BMW E46 Coupe's licence plate, follow these tips:

• Pay Attention to Screw Length: Consider the total thickness of your licence plate setup, including any screw covers, frames, or clear licence plate covers. Choose screws that are long enough to secure the assembly without being too long, as this can damage your car's finish.
• Use Washers and Spacers: Synthetic washers made from materials like nylon can help reduce rattling and protect the paint and reflective coating of your licence plate.
• Avoid Over-Tightening: Be careful not to over-tighten the screws, especially when attaching the OEM plate bracket to your vehicle. Over-tightening can cause the plastic nut inserts to pull out, requiring a trip to the dealer for repairs.
• Consider Screw Caps and Covers: While screw caps and covers are primarily for aesthetics, they can also provide additional protection against corrosion and theft. Choose covers that snap securely over the screw heads, providing a tight fit to deter thieves.

By following these guidelines and choosing the right anti-theft screws, you can securely install your BMW E46 Coupe's licence plate while deterring theft and maintaining the appearance of your vehicle. Remember to use the correct screw size and length, and consider adding washers and screw covers for enhanced security and protection.
