The external toothed washer has slightly curved teeth on its outer diameter, while the internal toothed washer has lightly curved teeth around its inner diameter. The combined toothed washer, also known as an internal-external toothed washer, integrates both internal and external teeth. These three types of washers operate on similar principles. The washer is typically installed between the bearing surface of the bolt or screw and the contact surface of the component being fastened. When tightened, the serrations embed into the contact surface, enhancing the stability of the connection. This design not only significantly improves the fastening effect but also effectively absorbs impacts and vibrations, boosting the anti-loosening performance of the parts. It helps prevent loosening caused by vibrations or torque, ensuring the stability and reliability of the components over long-term operation.
