Understanding License Plate Screw Sizes
The standard screw size for most vehicles’ license plates is determined by the manufacturer, but there may be variations in sizes among different manufacturers.
Standard Screw Size For Most Vehicles
The standard license plate screw size for most vehicles is typically 1/4-14-3/4-inch self-tapping screws. This measurement suits the majority of car brands and doesn’t require a pre-drilled hole, which adds to its popularity.
The threading on these screws makes them compatible with vehicles featuring nylon or plastic screw retainers. However, there are exceptions depending on the make and model of your vehicle.
Variations in Screw Sizes by Manufacturer
Different manufacturers may have variations in the screw sizes used for license plates. While the standard size is 1/4-14-3/4 inch self-tapping screws, some brands may use different specifications.
For example, Chevrolet vehicles typically use 10mm #14 x 3/4″ screws, while Honda vehicles may use either M6 x 1.0 x 20mm or 1/4-14-3/4 inch screws. Ford cars, on the other hand, commonly utilize 1/4″ (#14) x 5/8″ screws.
It’s important to check the specific requirements for your vehicle to find the appropriate screw size and ensure a secure fit for your license plate.
