Galvanized Iron Washer is a type of flat washer that is made from galvanized iron, a material that has been coated with a layer of zinc to protect it from rust and corrosion. The washer is a thin, flat, circular disc with a hole in the center that is used to distribute a load of a fastener, such as a bolt or a screw, over a larger area. The washer can also be used to prevent damage to the surface of the material being fastened. Galvanized iron washers are commonly used in construction, plumbing, and automotive applications, where they are used to provide a secure and reliable connection between two or more objects.
