Compare the 3 main types of washers

Washers are that pieces of hardware without which many operations in the manufacturing industries could have been impossible. They are used widely in the industrial sector for spreading the load or weight of the fasteners like a nut or bolt. The washers also act as a spacer between the fastener and the mating surface to prevent it from damages and lock the fasteners in place, no matter how strong the vibrations are. There are different types of washers available in the market that function differently. Therefore, it is crucial for industries to choose the type of washers that perfectly matches their manufacturing requirements. 


The market for washers has emerged exceptionally in the last few years. If you pick out the statistics, you can easily see the growth of Shim manufacturer in India. Different types of materials are used in the manufacturing of washers, but copper, being the best material, is mostly used to manufacture washers, and this can also be seen by counting the number of copper washers exporters in India. As there are numerous kinds of washers, most fall under the three main categories: Spring, Plain, and Lock washers. So,

let us discuss how these washers help the manufacturing sector in different ways:

Spring washers: Spring washers are known for their axial flexibility, which is greater than any other type of washers. They are used for holding the nuts & bolts in place and prevent their loosening due to vibrations. The different washers that come under the category of spring washers are:


Crescent Spring washer: A look-alike of a flat washer, crescent spring washers are slightly curved owing to which they provide flexibility in operations. The washers are used to support relatively light loads with a wide deflection range. 


Belleville washers: These cupped shaped washers are used for producing very high loads in small areas. The washers have the ability to dampen the vibrations and shocks to ensure the seamless processing of various industrial applications.


Wave spring washer: Curved in two directions, the wave spring washers are mostly used as spacers or cushions to prevent the mating surface from damages. They exert a compensating spring force and absorb shock.


Dome spring washer: With a similar appearance to Belleville washers, the dome spring washers are round at the sides. They are used in applications where a flatter surface needs to be created for more effective processing of applications.


Finger spring washer: These washers have three curved flanges and are used for dampening the vibrations and noise.


Plain Washers: Popular as flat washers, their outer diameter is larger than the inner diameter. The plain washers are used for distributing the load of the threaded fasteners and keep them in place even under conditions of strong vibrations. Below is the list of washers that fall under plain washers:


Fender washer: These washers distribute the force of the fasteners when tightened by providing more surface area that divides the load into thin or soft materials.


Flat washer: These are round, thin washers that are used distributing the load and correcting the hole size.


Finishing washer: Finishing washers are used in applications where a decorative and precise finishing to the surface is required. The washers grip light materials like fabric and others, securely away from the hole.


Torque washer: With a square hole and outer prongs, the torque washers prevent the bolt from spinning while fastening a nut. 


C-washer: With a slot cut from the center hole, the C-washers can easily be slide in and out of position to make things work efficiently.


Lock washers: Lock washers are the ones that make sure that the nuts and bolts do not turn, slip and loose at the time when the manufacturing applications are under process. They help in ensuring a fault-free working of industrial applications and reduce the chances of accidents & injuries. We are providing a list of commonly used lock washers:


External tooth lock washers: With several teeth on the outside diameter, the external tooth lock washers, bite into the surface of one surface to resist compression.


Internal tooth lock washers: Opposite from the external tooth lock washers, the internal ones have teeth inside diameter that bite into the fasteners to absorb shock & vibrations as well as to hold them in place.


Split lock washers: Also known as helical washers, these washers are normally used to fix fasteners in place and eliminate their movement to ensure continuous processing of several applications.


As you have read about the different categories and sub-categories of washers, you may have developed an understanding of how each washer varies from others on different terms. As a manufacturer, a person must have knowledge of how each washer can be used to process different industrial applications, so he/she can choose the best one for their industry.
