The toilet seat replacement parts kit is easy to install with a convenient and fast installation process. Simply push the toilet seat nut into the hole, place on the gasket, and tighten the bolt from the top—the screw will expand and secure itself into the hole. With built-in adjustment range and a compact design, it allows for easy installation, quick disassembly, and simple cleaning. These expanding toilet seat screws provide a secure fit for toilet lids, helping prevent instability. If your toilet seat shifts or moves, replace the worn plastic inserts with these durable fixing screws designed for top-fix toilet seats. This toilet seat fixing kit is ideal for replacing broken or old toilet seat hinges. Fits most standard WC toilet pans. Suitable for top-fix fitting toilet seats and back-to-wall units.
