Round screw diameter: 1.4 cm (The exact dimensions of each toilet seat nut are shown in the image. Please measure before purchasing to ensure proper function of your toilet seat.) High-quality material: The expansion ball is made of black rubber, the white screw with solid brass thread is made of nylon, the long screws and washers are made of 304 stainless steel, and the soft washers are made of ABS plastic. Sturdy and durable, rustproof and corrosion resistant, better than most plastic fasteners. Rustproof design: Plastic washers do not rust, making them superior to metal washers. When tightened, the screws compress the washers into the holes. Be careful not to overtighten the screw, as this will push through the washer. The screw has a solid brass thread for a non-slip, rust-proof seal. Easy to use: The toilet seat screws are inserted into the toilet's mounting holes. The rubber sleeves are threaded and simply insert into the holes at the top of the toilet. When the screw is tightened, they expand and lock into place, without the need for additional screws at the other end. Quick and convenient. Universal: 2 pairs/4 replacement toilet seat fasteners. If your toilet seat keeps moving, replace the unusable plastic inserts provided with a new lid fastener with these toilet seat fastener screws. The toilet seat fasteners fit most standard toilet seats with a 14-18mm hole diameter. Product description: Features: Fits most standard toilet seats. Suitable for 14-18mm toilet seat holes, universally applicable. Specifications: Material: Rubber, ABS, stainless steel, nylon. Dimensions: See picture. Quantity: 2 pairs/4 pieces.
