What Is The Function Of A Gasket

Washers are widely used in load-bearing and non load-bearing structures of general mechanical products, and can be found in many places in our daily lives. So what is the function of the gasket?
The function of the washer is to protect the surface of the connected component from being scratched by the nut, dispersing the pressure exerted by the nut on the connected component. At the same time, the sloping tip of the washer presses against the support surface of the nut and the connected component, which also has a relaxing effect.
A washer refers to a component, usually a flat metal ring, that is placed between the connected component and the nut; There are many types of gaskets, which vary in size, thickness, material, and function.
