Product Description
A washer is a thin, flat piece of material used to distribute the load of a fastener (like a bolt or nut) and to prevent damage to the surface being fastened. Washers also help in reducing friction, preventing loosening, and providing insulation. There are various types of washers, including flat washers, spring washers, and lock washers, each serving a specific function in fastening applications.

There are three types of gaskets: non-metallic gaskets, metal composite gaskets and metal gaskets. And there are flat gaskets, spring gaskets, locking washers, stop washers, etc. Gaskets are mostly used for mechanical seals between two objects. They can be filled in the irregular surface of the machined surface or placed on a regular plane to enhance the sealing performance. The function of the gasket is to increase the contact area between objects, disperse the pressure, and play a protective role, but it does not necessarily have a sealing effect.
There are three main types of gaskets. One is non-metallic gaskets, such as gaskets made of rubber, asbestos rubber, flexible graphite, polytetrafluoroethylene, etc., all belong to the category of non-metallic gaskets. Their common feature is that the cross-section is basically rectangular. Second, metal composite gaskets, such as common metal wrapped gaskets, metal wound gaskets, etc. The third type is metal gaskets, which are also widely used. They are also rich in form, such as metal flat gaskets, corrugated gaskets, annular gaskets, toothed gaskets, lens-shaped gaskets, triangular gaskets, double cone rings, C-shaped rings, hollow O-rings, etc. There are more types of gaskets, including flat gaskets, spring gaskets, locking washers, stop washers, etc., and their functions are also different. Among them, flat gaskets only increase the contact area, but have no anti-loosening effect, while elastic gaskets can increase the area and effectively prevent loosening. A unique advantage of locking washers is that the lock core will generate a backward thrust, which has a good anti-loosening effect. As for stop washers, their inner ring will have a raised fixing foot, and the outer ring will even have 3-4 fixing feet, which can not only prevent loosening, but also have a good fixing effect.
