Honda Genuine License Plate Lock Bolts for Passenger Cars (Set of 3 for Automobiles) Honda genuine license plate lock bolts prevent license plate theft simply by replacing the screws. They are also rust-resistant, have a glossy finish, and give a clean appearance. As they are MacGuard products, they can be used regardless of the manufacturer. This is a set of 3 bolts with a neck length of 20mm. Although there is some wear and tear, I believe it is a product that can be used sufficiently. This is a set of 3 for passenger cars.
