A double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.
