Honda Genuine License Plate Lock Bolts for Kei Cars (Set of 4) Logo stickers are not included. Please prepare your own. Honda genuine license plate lock bolts prevent license plate theft simply by replacing the screws. They are also resistant to rust, have a glossy finish, and give a clean appearance. These are McGard products, so they can be used regardless of the manufacturer. The bolt length under the head is 20mm, and this is a set of 4. There are no noticeable scratches or stains, and I think you will be able to use them comfortably.
