Sealing screws, also known as self-sealing screws or sealing fasteners, are specialized screw components designed to provide a secure and leak-proof seal in various industrial and mechanical applications. These screws feature a unique design that incorporates a sealing element, typically a resilient O-ring or washer, which is integrated into the screw’s structure. When the sealing screw is fastened into place, the sealing element creates a tight seal between the screw and the mating surface, preventing the passage of fluids, gases, or contaminants.
