Size: Black expansion ball diameter: 1.8 cm (unexpanded). Length: 4 cm. White screw size: 4.5 x 0.5 cm. Nylon expansion nut size: 3.7 x 1.8 cm. Washer diameter: 1.4 (The detailed size of each toilet seat nut is in the image; please measure before purchasing to ensure it fits your toilet seat properly.)

Excellent Material: The expandable ball is made of black rubber, the white screw with solid brass threads 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: The plastic washers won't rust, better than metal washers.

When you tighten the bolts, the washers compress into the holes. Be careful not to overtighten the bolt so much that it pushes through the washer. The screw has a solid brass thread inside that is non-slip and rust-resistant. Easy to use: Place the toilet seat bolts into the toilet mounting holes. The rubber grommets have a threaded section so you can simply push them into the holes in the top of the toilet bowl. When you tighten the screw, it expands and contracts in the hole, eliminating the need for a bolt on the other end. Convenient and time-saving. Universal: 2 pairs/4 replacement toilet seat bolts.
