One of the most significant advantages of ceramic-coated self-drilling screws is their ability to resist galvanic corrosion. In environments where different metals are in contact, galvanic corrosion can occur, leading to deterioration and failure of the screws. The ceramic coating acts as a barrier between the screw and the surrounding metal, preventing this corrosion from occurring. This makes these screws an ideal choice for use in marine, offshore, and other environments where corrosion is a major concern.
