What is a washer

?

Washers are made in the form of rings and in different thicknesses. They have a hole in their heart. Their position is between the body and the vertebra. About their gender, it should be said that they are mostly metal or rubber. The bolt and nut in which the washer is to be used is a determining factor for choosing the material of this tool. The thickness of the piece and the size of the hole diameter and the diameter of the disk are the things that cause the difference between the types of washers. Washers have two main tasks; First: distributing the pressure of the nut or the head of a fastener such as a bolt and nut evenly and without damaging the surface by the split washer, second: ensuring that the nut is pressed on a flat surface to reduce the possibility of loosening over time.

✔️ Materials used in Washer Buy

Washers are made of various materials, the most popular of which are galvanized carbon steel and stainless steel. Carbon steel is stronger than stainless steel, but stainless steel does not rust or corrode like carbon steel. Other metal washers include zinc, copper, brass, and iron. You can also find specialty washers such as plastic washers, rubber washers, ceramic washers, and phenolic washers. There are many special types of gaskets that go beyond general use to help prevent corrosion, reduce friction, leak, isolate, prevent loosening or pressure distribution, improve appearance, and serve as insulators in electrical applications. In the market, washers are available in different sizes as standard, and we choose and buy one of the washer models according to the needs of the part and how to install it. However, choosing the right type of gasket for a project can be more complicated than it seems. This guide lists and describes many types of washers and their recommended purposes.

✔️ The most important use of washer

The most common use of this part is load distribution. Now, apart from the main item mentioned, we have prepared for you a list of other uses of this widely used piece. Absorbs vibration: The anti-vibration gasket protects one object from the aggressive vibrations of another object. In order to eliminate the vibration, we must use a soft gasket, for example, rubber and urethane are suitable for this purpose. Therefore, never use a metal washer to absorb vibration. It prevents the penetration of liquids: for this purpose, as in the previous case, soft gaskets should be used. Gaskets that have this capability are usually used in water connections. Fills the empty space between joints: Another use of the piece is to fill the empty space between joints. Makes the main washer not bend due to pressure: Suppose in a connection, the pressure applied by the screw to the main washer is so high that there is a possibility of the washer bending. The solution to this problem is to use a smaller washer under the main washer. The use of washers aims to protect the main part: sometimes in a connection due to the rotation of the nut, the possibility of corrosion or damage to the main part increases. So we must use a washer in this situation, because the washer can maintain the strength of the piece by creating friction. Prevents bolts and nuts from loosening: A proper washer can keep bolts and nuts tight together.

✔️ How is a gasket measuring?

What is important in measurement is the following. Disc thickness Hole diameter and disc diameter Edge arc and surface

✔️ Category Washer Types

Based on the application and performance of washers, the following categories can be generally defined for washers: Plain washer Lock washer Spring washer

✔️ On the other hand, each of these categories also has the ability to be separated into smaller parts with different design and production:
