Spring washers are often called spring washers in the screw industry. Its materials are stainless steel and carbon steel, and carbon steel is also iron. Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. It is characterized by low cost, convenient installation, and suitable for parts that are frequently disassembled and assembled.

The role of spring washers

1. The function of the spring washer is that after the nut is tightened, the spring washer gives the nut an elastic force to tighten the nut so that it is not easy to fall off. The basic function of the spring is to give a force to the nut after the nut is tightened to increase the friction between the nut and the bolt.

2. When using spring washers, flat washers are generally not used (except to protect the surface of the fastener and the installation surface, use flat washers and spring washers).

Install a spring washer under the nut to prevent the nut from loosening.

The bolts connecting the motor and the frame generally require spring washers, because if the motor vibrates without the spring washers, the nuts will loosen. The fasteners on the vibration equipment are generally equipped with spring washers, and the flanges generally do not need to be installed. The addition of spring gaskets on the flange is related to the medium flowing in the pipeline. If it is easy to produce pulses, it is best to add a spring washer, and there is a high-speed fluid, and the diameter changes frequently. Do not promote.

Advantages and disadvantages of spring washers


①The spring washer has good anti-loosening effect;

②The spring washer has good anti-vibration effect;

③Low manufacturing cost;

④The installation is very convenient.


Spring washers are greatly affected by materials and processes. If the material is not good, the heat treatment is not well grasped, or other processes are not in place, cracks are prone to occur, so you must choose a reliable manufacturer.

The difference between spring washer and flat washer

The spring washer can prevent loosening and increase the pre-tightening force. Flat washers do not have this function. It can be used to increase the fastening contact area, prevent the friction between the bolt and the workpiece, and protect the connector surface from the influence of the bolt. When tightening the nut, the surface of the workpiece was scratched.

However, some important connections, such as places where power is transmitted through friction generated by compression, cannot be used with spring pads. If the rigidity of the connection is reduced, an accident may occur. The spring washer can be omitted. When the strength of the connecting piece is low, use flat washers or flange bolts to increase the contact area. When there are vibrations, pulses, and medium temperature fluctuations, spring washers must be used.
