Core functions

1. Uniform pressure distribution: In automotive assembly, when the nut and bolt are tightened, the washer can evenly distribute the pressure applied by the nut onto the contact surface. For example, in wheel installation, the nut washer ensures that the nut pressure is evenly distributed on the wheel hub, avoiding excessive local pressure that can cause deformation of the wheel hub, effectively extending the service life of the wheel hub, and ensuring driving safety. ​

2. Anti loosening fastening: The special tooth shape or structural design of the washer increases the friction between the nut and the installation surface, effectively preventing the nut from loosening due to vibration during vehicle operation. Various types of nut connections and washers in the engine compartment can ensure that the nuts remain securely fastened in the continuous vibration environment of the engine, preventing dangerous situations such as component detachment caused by loose nuts. ​

3. Protecting connecting components: It can isolate the nut from the connected components to prevent the nut from scratching or wearing the surface of the connected components during tightening or vehicle vibration. At the connection between the body and chassis, washers protect the metal surfaces of the body and chassis, avoiding the impact of metal shavings generated by friction on component performance, while reducing the risk of corrosion and improving the overall durability of the vehicle.
