When installed correctly, center caps should not require any special care. If your center cap screws are backing out or coming loose, you can use a small amount of blue thread locker to assist.
Push through style center caps do not use any hardware to affix them to the wheels. These are inserted through the center from the backside of the wheel prior to installing the wheels onto your vehicle.
