• Function

1.Preventing loosening: It can be placed between the fastener and the connected component to increase the friction force, preventing the fastener from loosening due to vibration and other factors, thus ensuring the reliability of the connection. In the operation of construction machinery, there are often vibrations. The 8T - 4121 washer can play a good role in preventing loosening and ensuring that each part remains in a stable connection state.

2.Protecting the connected components: When the fastener is tightened, it can avoid direct contact between the fastener and the surface of the connected component, preventing the surface of the connected component from being scratched or deformed by the fastener. For example, in the engine, it can protect the engine block and other components to ensure their surface integrity and service life.
