Replacement screw for sink mixer 2 screws with crescent washer

The product shown in the picture is a set of sink faucet screws, also known as toilet faucet mounting screws. These screws are used to secure the toilet faucet to the bowl. The set usually consists of metal screws, nuts, waterproof rubber rings, and a crescent-shaped metal ring. The rubber rings are used to ensure a tight seal, prevent water leakage between the faucet and the sink, and also prevent friction. These screws are an essential part of the faucet repair kit and are available in different sizes to fit most toilets with one or two bolts. These screws may need to be replaced if they are old, rusty, or if the rubber rings are damaged, which could lead to instability of the faucet or water leakage from the faucet opening.
