What are the differences between spring washers and flat washers?

The function of a flat washer is to increase the contact area between the screw and the machine. It eliminates the damage to the machine surface caused by the spring washer when removing the screw. More often, it is used as a supplementary pad.

Advantages of flat washers:

1. By increasing the contact area, it can protect the components from damage;

2. By increasing the contact area, it reduces the pressure between the nut and the equipment, thus providing protection.

Disadvantages of flat washers:

1. Flat washers cannot provide shock resistance;

2. Flat washers do not have anti-loosening function.

The function of a spring washer is to give the nut a spring force after tightening the nut, thereby increasing the friction between the nut and the bolt, making it less likely to come loose. Of course, when choosing a spring washer, attention should also be paid to its advantages and disadvantages.

Advantages of spring washers:

1. Spring washers have good anti-loosening effect.

2. Spring washers have good shock resistance effect.

3. The manufacturing cost is low, and it is convenient to install.

Disadvantages of spring washers:

The spring washer is greatly affected by the material, process, and other aspects. If the material is not good, the heat treatment is not well controlled, or other processes are not done properly, it is easy to crack. Therefore, it is necessary to choose a reliable manufacturer.

Application scenarios:

1. Generally, in cases where the load is relatively small and does not bear vibration load, only flat washers can be used.

2. In cases where the load is relatively large and bears vibration load, flat washers and spring washers must be used in combination.

3. Spring washers are basically not used alone, but are used in combination.

During actual use, due to the different focuses of flat washers and spring washers, in many cases, the two are used together as a pair to achieve the advantages of protecting components, preventing nuts from loosening, and reducing vibrations. This is an excellent choice.
