In the screw with nuts, the role of the gasket is mainly: increase the contact area, reduce pressure, prevent loosening, protect the Bai protect parts and screws.
A gasket is a mechanical seal between two objects, usually used to prevent pressure, corrosion, and natural pipeline expansion and contraction leakage between the two objects.Since machined surfaces cannot be perfect, irregularities can be filled with gaskets.
Gaskets are usually made of sheet materials such as pad, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, glass fiber, or plastic polymers (such as Teflon).Gaskets for specific applications may contain asbestos.
