304 Metal screw washer

304 Metal screw washer Composed of disc-shaped metal sheets (usually carbon steel or stainless steel), washers are used to distribute the load of bolts. Before threading the bolt through the object, first thread it through the washer. The function of the washer is to evenly distribute the load of the bolt to prevent loosening. If the gasket ruptures or fails in any other way, the bolt may gradually loosen over time. In order to protect gaskets from corrosion related failures, manufacturing companies often handle their gaskets during the production process. Here are five common corrosion protection treatments for gaskets. Paint-coat：Perhaps the most common corrosion protection treatment for gaskets is coating. According to the material used to manufacture the gasket, it may rust or corrode when exposed to moisture. For example, high carbon steel is prone to rusting and corrosion. However, a layer of coating can be applied on the gasket to prevent this from happening. Zinc coatings are…
