2-Pack Top-Mount Toilet Seat Expansion Bolts
All metal parts of these expansion bolts are made of thickened stainless steel. The material adapts well to humid bathroom surroundings, resists corrosion caused by long-term contact with water and common cleaning products, and retains stable performance after long time daily use.
The built-in expansion structure will expand and press tightly against the inner wall of the mounting hole after you tighten the screw. It holds the toilet seat firmly in place, effectively reduces unnecessary wiggles when you use the toilet, and brings more reassuring daily use experience.
Our store provides responsive pre-sales consultation for you if you have any doubts about product adaptability or installation guidance. We also arrange timely after-sales support to handle issues you meet after receiving the package, and help you figure out proper solutions.
