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.

A 4PCS fix anchor is a type of anchoring system designed to provide strong, secure holds for various construction materials, particularly in masonry and concrete settings. The term 4PCS refers to the design consisting of four components, which typically include an anchor bolt, a washer, a nut, and a sleeve or expansion component. This multi-part construction allows the anchor to offer enhanced grip and stability, distributing weight and resisting pull-out forces more effectively than simpler designs.
