Types of bolts and nuts
⏬ Types of screws and their use ⏬

The screws that exist in the market are used for different purposes and have been produced and launched in the market in a very high variety. In the rest of the article, we intend to introduce a number of screws to you:

🔽 Car screws 🔽

To produce car screws from yellow and silver inclined process It is used in blue. In addition, the coating used for these screws is made of zinc. Machine screws are among full thread screws and due to the use of zinc coating to produce these screws, they are usually used more in the electronic industry.

🔽 metal screw /b>

These types of screws are usually used to connect metal sheets and different metals together. Of course, it is sometimes observed that metal screws are also used to connect fiberglass and plastic. People who intend to connect metal to wood, the best screws that can be used for this purpose are metal screws. The reason for this is the presence of small threads with a short distance on this type of screw. There are different types of metal screws in the market, among which we can refer to screws with washers and square screws.

🔽 Hexagonal screw Gosh can be introduced as the most widely used type of screw available in the market, which has a very high sales. In order to be able to open and close the hex screws, you must use a French wrench. The hexagon screw is also available in the market in two models, half thread and full thread, and each user can choose and buy the right type according to their application. Usually, steel and galvanized coating are used to produce these screws. But in some models, we see that these covers are not used to produce the above screws.

🔽 Wood screw 🔽

Wood screw is one of the semi-threaded screws available in the market and it is used to connect wooden items. This screw is sold in two colors, silver and yellow. The coating used for wood screws is made of stainless steel or zinc. It is called a screw that is very similar to a car screw, and the only difference is that there is a cut in the head of these screws. Usually, pointed screws are used in places where the purpose of tightening the screw is high torque. A drill tip is one of those screws that does not require a primary hole to be used and can open its own way. Steel metal with zinc coating is usually used to produce the screw with a drill tip. The part of the drill tip screw series has two hexagonal or washered modes.

🔽 Elevator screw 🔽

Elevator screws for connecting surfaces that have material They are plastic and soft. Among the applications of these screws, we can mention their use in conveyor belts. Elevator screws consist of a series with a large, flat diameter and a neck that has a square shape and is narrow. Of course, some elevator screw models have a triangular shape in the serial part. These screws usually reduce the amount of vibration.

🔽 Nut screw 🔽

Nut screw is used to tighten different surfaces. Nut screws have various models, among which we can point out the pointed model, khor and Allen screwdriver. These pages have a depression in their secret part, and in order to be able to open and close these screws, you must use a special wrench.

These screws look like wood. But their head part is hexagonal or quadrangular and their ends are conically threaded. The above screws are usually used when a high torque is needed to tighten the screw.

⏬ types of beads ⏬

The number of nuts available in the market is also very large, just like the screws, and to choose the right option, you must first familiarize yourself with them. Below we introduce and examine the types of nuts.

🔽 Square nut 🔽

Because square nuts have a large seating surface. If you use a wrench to connect them, you can connect these nuts to the desired surface without vibration, and the presence of a large seat surface has increased the friction of these screws. As a result, if you use this product to make your connections, your connections will have higher resistance. Hexagons have a higher percentage of looseness than square nuts. But due to having two more corners, the wear percentage of their surface is less compared to square nuts, which is one of the advantages of these nuts. Among the other advantages of hexagonal nuts, it can be mentioned that in order to rotate square nuts, one must rotate the nut at an angle of 90 degrees. But for the rotation of the hexagonal nuts, rotation with an angle of 60 degrees will be enough. Hexagonal nuts are marketed in two different types, and these two types include the following:

🔽 Narrow hexagonal nut 🔽

The above nuts are used in places where the length of the thread is short. In addition, when we need more than one nut to connect to the desired surface, we use narrow hexagon nuts. Heavy hexagon nut

The heavy hexagon nut is usually used for screws whose diameter is more than 40 mm. In addition, screws that are under the influence of high force usually use heavy hexagonal nuts.

🔽 machine nut It is produced and marketed in two types: hexagon and square. The above beads have very small dimensions and these beads can easily be considered among the smallest square and hexagonal beads available in the market.

🔽 Locking bead with nylon ring 🔽

In this type of beads, a ring made of nylon is used to produce one side of the bead threads, which This ring is smaller than the size of the screw. In fact, the presence of this ring makes it difficult to move the screw and its function can be compared to glue. The connections made using these nuts are very resistant. Since nylon polymers are used to produce these nuts, they cannot be used in places with high temperatures.

🔽 Locking nut with nylon components 🔽

Nylon locking nuts are nuts that are made from pieces of nylon in different parts of the thread. The locking percentage of the above beads is lower than nylon ring beads, and these beads can be considered a disposable bead. Because after one use, the resistance of these beads decreases and it cannot be used again.

🔽 eye bead An eye is actually a series of threaded rings that are usually used in heavy objects so that when there is a need to move these objects by crane and other machines, the work of moving can be done more easily.

🔽 closed head nut 🔽

closed nuts have a dome-like surface in their end part. These nuts are connected to the end part of the threaded screws and rods with a good fit and prevent them from hitting body parts or other objects. Of course, closed nuts with long series are also available in the market, which covers more thread surface.

🔽 Washer nut The washer basically acts as an intermediary between the body and the nut, and plastic or metal is used for its production. The main function of the washer is to distribute the load of bolts and nuts, and this work leads to the prevention of deformation of the work piece. Nuts with washers are nuts that have a wide plate on one side, and when the number of connections is high, their use leads to an increase in assembly speed. In principle, nuts with washers lead to the prevention of the washer being left in sensitive places, especially in dark parts.

🔽 grooved nut Grooved nuts are nuts that have a number of grooves on one side for the pin to pass through. Basically, the above pins lead to increase the resistance of the connection against impact and vibration. Installing or removing grooved nuts is easier than other locking nuts.
