Easy Installation The toilet seat fixing kit comes with all fittings for installation. Insert the toilet seat screws into the toilet mounting holes. The threaded sections are equipped with rubber grommets, which can be easily pushed into the holes on the top of the toilet pan. Tightening the screw causes it to expand and secure itself in place without requiring a bolt on the opposite end. Premium Material The soft close toilet seat hinges are constructed from high-quality rubber and metal, offering durability, strength, and stability. The rubber components provide excellent resilience and expansion performance. Additionally, the rubber cover helps protect the screws from dirt, wear, breakage, and rust. Package Includes This package includes 4 sets of toilet hinge replacements with expansion rubber bolts, nuts, washers, and screws. Once installed, the toilet seat and hinge fixings are designed for long-term use. Universal Size The toilet seat hinge fittings are compatible with 14–16mm mounting holes. Please refer to the product images for sizing details before purchasing. Wide Application These toilet seat hinges fit most standard toilet seats with top-fix hinges. Ideal for replacing back-to-wall or wall-hung toilet pans, this kit serves as a reliable fixing solution for WC toilet seats.
