Universal Toilet Seat Mounting Screws – 4-Piece Pack – Top Mount – Fits 14-16mm Hole Diameter. Does your toilet seat frequently become loose, shift, or noisy? Often, the problem isn't the toilet seat itself, but rather the old, worn mounting screws. This 4-piece universal mounting screw set offers a simple and effective solution. Thanks to the expansion principle—when the screws are tightened, the rubber sleeves expand—they securely hold their positions in the mounting holes. The end result: a stable, wobble-free toilet seat. The clever expansion design makes installation a matter of seconds: Insert the screws into the mounting holes of the toilet seat. Tighten the screws—the rubber sleeves expand and automatically lock into place. Done! The toilet seat is securely in place and won't shift. No need to laboriously tighten bottom nuts or hard-to-reach screws. Installing each screw takes only minutes. The set includes 4 complete mounting screws, plus rubber sleeves. This accessory set is sufficient to replace both hinges of a standard toilet seat. The rubber sleeves are approximately 4 cm (1.57 inches) long, suitable for most standard hole depth toilets. These mounting screws are designed for top-hinged toilet seats and fit mounting holes from 14 to 16 mm in diameter. Please check your toilet's mounting hole diameter beforehand. They are ideal for replacing old, worn, or rusty mounting hardware. These mounting parts are universally designed and fit most standard toilet seats. An expansion mechanism prevents unwanted movement. Your toilet seat will remain stable and secure even with frequent use. Say goodbye to annoying creaking and shifting. This set is made from a combination of robust materials: rubber sleeves, galvanized metal screws, and plastic components (nylon and ABS) finishes. It ensures rust resistance, corrosion resistance, and durability, even in the humid environment of a bathroom. Quantity: 4 mounting screws with rubber sleeves.
