Screw Sizes For Number Plates: What Fits Best?

Number plate screw size is an important consideration for motorists wanting to personalise their number plates. The governing body responsible for number plate laws in the UK is the DVLA, which has strict rules about how number plates should be displayed. The main issue the DVLA wants to avoid is obscuring the characters on a number plate. The average number plate screw size is 1/4-14-3/4 inches, but different car brands use different types of screws, so finding the right size can be tricky.

Number plate screw colours

Number plate screws are available in a variety of colours, allowing for customisation and aesthetic appeal when securing vehicle registration plates. The most common colours available are white, black, yellow, blue, and green.

White, black, yellow, and blue screws are widely available from various retailers and are often sold as part of a fixing kit for number plates. These colours are designed to blend seamlessly with the background of the number plate, providing a discreet and unified appearance.

Green number plate screws are also available and are specifically marketed for use with Electric Vehicle (EV) plates. This colour option not only serves a functional purpose but also helps to distinguish EV number plates from traditional plates, contributing to a more sustainable and environmentally conscious image.

In addition to the standard colours, orange screws have also been mentioned as an option for number plate fixings. This colour variation offers an alternative for those seeking a less conventional appearance or for specific automotive applications.

The colour of the number plate screw is an important consideration not only for aesthetic reasons but also for ensuring compliance with vehicle regulations. By offering a range of colour options, drivers can choose the most suitable match for their number plates, contributing to a neat and integrated overall look.

Screw placement rules

When placing screws on a number plate, it is important to follow the rules and regulations set by the governing body, the DVLA. Here are some guidelines to ensure compliance with the law:

Placement and Display

The placement of screws on a number plate is crucial. The law states that screws should not obscure the characters on the plate. This means that screws should not be placed in the middle or next to any characters, as this can change the way the plate is displayed. The number plate should always be clearly displayed, with screws placed on the far left and right of the plate or in areas that will not affect the visibility of the characters.

Screw Type and Size

Different car brands use different types and sizes of screws for number plates. It is important to research the correct screw type and size for your vehicle to avoid damage. The average number plate screw size is 1/4-14-3/4 inches, but threading may vary, so it is essential to check the compatibility of the screws with your vehicle to prevent costly repairs.

Colour Considerations

The DVLA regulations specify that the front number plate must have black characters on a white background, while the back plate should have black characters on a yellow background. To avoid compromising the legibility of the number plate, it is recommended to use screws in yellow, white, or black colours. These colours ensure that the screws blend in with the required background colours without affecting the reflectivity or clarity of the plate.

Alternative Methods

While screws are a common method for securing number plates, there are alternative options such as sticky pads, brackets, and lipped brackets. These methods can be used in conjunction with screws for added security. Sticky pads, for example, provide a strong adhesive that keeps the number plate in place, but they can be tricky to remove cleanly. Brackets, on the other hand, allow for easy installation and removal, but may not provide the same level of security against theft.

Legal Compliance

It is important to note that the DVLA has strict rules about how number plates should be displayed, including the use of screws and fixings. Using the wrong type or placement of screws can result in fines or failure to pass inspections. Always refer to the latest regulations provided by the DVLA to ensure your number plate complies with all legal requirements.

Average screw size

The average screw size for a number plate is 1/4-14-3/4 inches. However, it's important to note that different car brands use different types and sizes of screws for their number plates, so finding the right size can be tricky. If you're replacing your number plate with a new vehicle, it's crucial to do your research to avoid damaging your car with the wrong bolts and screws.

Number plate screws are typically available in two standard sizes: 19mm and 24mm in length, with a diameter of 4.8mm. These screws are designed to securely fasten your number plate to your vehicle and are available in various colours, including yellow, black, white, and blue.

When purchasing number plate screws, you can choose from different types, such as self-tapping screws or screws with hinged flip-top caps. Self-tapping screws are convenient as they can tap their own hole as they are pressed into the bumper material. On the other hand, screws with hinged flip-top caps offer a quick and effective way to brighten up your number plates while keeping them securely in place.

In addition to the screw size, it's important to consider the threading of the screws. Using screws with the wrong threading can damage the threads, leading to costly repairs. Therefore, it's always recommended to research the specific screw requirements for your vehicle before making any purchases.

It's worth noting that there are regulations governing the use of number plate screws. The DVLA, the governing body responsible for number plate laws in the UK, states that screws should not obscure the characters on the number plate. This means that screws should be placed on the far left and right of the plate or in a space that does not affect the display.

Self-tapping screws

The process of installing a self-tapping screw is straightforward. First, ensure you have the correct size and thickness of the screw for your application. Mark the precise location for the screw, and if desired, drill a pilot hole. Place the tip of the screw into the hole or marked position, ensuring your drill driver or screwdriver is at a 90-degree angle for a straight insertion. Start turning the screw manually or with a drill driver, applying gentle and consistent pressure. As the screw turns, it will create threads within the material. Continue until the head of the screw is flush with the surface. Check the alignment and tighten the screw if needed.

When purchasing self-tapping screws for number plates, ensure you select the correct size and type of screw for your vehicle. Number plate screw kits typically include self-tapping screws made of stainless steel to prevent rust and corrosion, along with ABS plastic caps in various colours to match your number plate. The standard size for number plate screws is 3/4" length, and you will need to drill a 4mm hole for installation.

Screw alternatives

When it comes to securing your number plate, there are a few alternatives to using screws. The most popular option seems to be sticky pads. Sticky pads are an easy and quick way to secure your number plate without having to make any modifications or drill into your vehicle. They provide a strong adhesive that won't come off easily, but this also means that they can be tricky to remove cleanly, so you must align your number plate properly before securing it.

Another option is a number plate holder, which only partly uses screws but does not require you to drill into the plate itself, keeping it pristine. Number plate holders act as a casing for your number plate, providing reliable and durable protection that is much more difficult to remove. They are available in chrome or black, and you can purchase a screw pack separately if needed.

Lipped brackets are another way to secure your number plate without using screws. They frame the entire plate, providing a more secure option compared to regular brackets, where plates can be easily slid in and out. Lipped brackets also secure number plates in a way that doesn't alter their display, ensuring compliance with DVLA regulations.
