Its shape is like a round ring. Before tightening the nut and bolt, it is fitted on a stud or bolt. It is used to ensure the tightness of a joint, screw, etc., and make it easier to unscrew the nut and bolt and keep their threads secure.
Even if the diameter of the bolt in which the bolt is to be fitted is larger than the diameter of the bolt, with the washer’s help and the nut, the bolt can be tightened easily.
1 Conical Washer
A conical washer is also known as a Belleville washer and in some cases a coned-disc spring. It is a conical shell that can be loaded statically or dynamically along its axis.
2 Dome Washer
Dome washers have a high load capacity while having a low overall deflection. Dome washers, also known as semi-spherical washers, have the shape of a truncated sphere.
3 Fender Washer
A flat washer with an outer diameter that is larger than its center hole is known as a fender washer. In comparison to most flat washers, they are constructed from a thinner gauge of metal and are intended to distribute the load on thin sheet metal.
4 Internal Tooth Washer
The teeth of an internal tooth lock washer project radially inward to bite into the bearing surface. The purpose of the internal tooth lock washer is to stop a nut or bolt head from losing due to the strut action created by the teeth.
5 External Tooth Washer
To secure nuts, external tooth lock washers are used. External tooth washers, also called Star Lock Washers, are serrated washers that exert pressure on the installation surface with their teeth.
6 Shoulder Washer
A shoulder washer protects fasteners, wires, and shafts from moisture and electricity. It has an attached sleeve, or bushing, at one end that resembles a standard flat washer on the other.
7 Countersunk Washer

8 Split Ring Washer
Split ring washers employ friction to stop bolted joints from becoming loose. They have an intricately twisted and split ring with two rough edges.
9 Split Washer
The crescent spring washer is also called a curved spring washer. The shape of a crescent washer is similar to a flat washer that has been slightly curved to apply minimal pressure and maintain flexibility.
10 Torque Washer
In order to prevent bolts from losing over time, torque washers are designed as follows: The bolt is anchored in place by four prongs that pierce the material.
