Familiar with the bolt:
Bolt is one of the components of the connection that is used to connect two or more pieces. The screw as a long and numerous components has fine lines.
Nut: The physical vertebra is a circular, round or polygon that is threaded inside the hole. The beads are auxiliary bolts to keep the screws tighter in their torsion path. The so -called nuts and screws are fastened with pistil and male.
Threads and screws should have a specific proportion to the thread and groove of the vertebrae to cause the screw to rotate properly. The beads are usually made of steel, iron or other metals, but are also made for plastic screws of plastic beads.
The types of screws and their application
The screws available in the market are used for various uses and have been produced and marketed in a very high variety. Below we are going to introduce you to a number of screws:
Car screw
use yellow and silver -blue processor to produce car screws. In addition, the coating used for these screws is zinc. Car screws are one of the full thread screws and because of the use of zinc coating to produce these pages, they are commonly used in the electronics industry.
Metal screw
These types of screws are commonly used to connect different metals and metals. However, it is sometimes observed that the metal screw is also used to connect fiberglass and plastic. People who want to connect metal to wood are the best screw they can use to do this. The reason for this is the presence of small threads with a short distance on this type of screw. There are various types of metal screws in the market, including gaskets and quadrilaterals.

Six -ear screw
Hexagonal screws can be introduced as the most widely used type of screw available on the market, which has a very high sales. You must use the French wrench to open and close the six screws. The hexagon screws are also marketed in both semi -threaded and all thread models, and each user can choose and purchase the appropriate type according to the type of use. Usually steel and galvanized coating is usually used to produce these screws.
Wood screw
Wood screw is one of the semi -thread screws to the market and is used to connect wooden appliances. The screw comes in both silver and yellow colors. The coating used for wood screws is made of stainless steel or zinc.
The tip of the tip
The tip of the tip is actually a screw that is very similar to the car's screw, and the only difference with the car screw is that there is a cut in the head of these screws. Typical screws are usually used in places where the screws are high in the upper torque.
Drill
The drill tip is one of those screws that does not require the original hole to use and can open its way. The drill tip is usually used with zinc coating steel. The drill tip bolt series has two hexagonal modes or replica.

Brain screw
Brain screws are used to tighten different surfaces. Brain screws have a variety of models, including the sharp model, the screwdriver and the Allen. These pages have a recess in their series and you must use a special wrench in order to open and close these screws.
Log screw
These screws look like wood. But their series has a six or quadrilateral mode and the end is conical. The above screws are usually used when the screw requires high torque.
Types of vertebrae
The number of beads on the market is as high as the screws, and you need to know them first to choose the right option. Below we introduce and examine the types of vertebrae.
The rectangular bead
Because the rectangular beads have a large surface area, if you use a wrench to connect them, you can attach these nuts to your desired surface without tremor and the large seat surface increases the friction of this screw. Have been. As a result, if you use this product to do your connections, your connections will be more resistant.
Hexagonal beads
hexagonal beads have a higher percentage of shock than rectangular beads. But because of its two corners, the percentage of their surface wear is lower than the rectangular beads, which is one of the benefits of these vertebrae. Other benefits of hexagonal beads include that to rotate the rectangular beads, one must rotate a 2 degree angle. But the rotation of the hexagon beads at an angle of 2 degrees will be enough. The hexagonal beads are marketed in two different types, including the following:
Hexagon
The above vertebrae are used in places where the thread is low. In addition, when we need more than one bead to connect to the desired surface, we use narrow hexagonal beads.
Heavier
Heavy hexagonal nuts are commonly used for screws with a diameter of more than 2 mm. In addition, the screws that are affected by the high force usually use heavy hexagonal beads.

Car nut
The car nut is manufactured and marketed in two types of six ears and rectangles. The above beads have very small dimensions and can be considered one of the smallest rectangular and hexagonal beads on the market.
Eye vertebrae
Eye vertebrae are actually referred to as a series of threaded rings that are commonly used in heavy objects to make it easier to move when there is a need to move these objects by crane and other machinery. .
Closed bead
The closed beads in their bottom have a dome -like surface. These beads fit well to the end of the threaded screws and rods, preventing them from colliding with the organs or other objects. Of course, the long -series beads are also marketed, with higher the amount of thread covering.
Washer beads
Washer acts as a mediator of the body and nut and is used to produce plastic or metal. The main task of the bolt is the distribution of the bolt, which will prevent the deformation of the workpiece. The beads are called vertebrae whose one side has a wide plate and when the number of connections is high, their use will increase assembly speeds. In essence, the replica beads prevent the gasket from staying in sensitive places, especially in the dark places,
Groove bead
Grooved vertebrae are referred to as beads with a number of grooves on one side of the pin. In essence, the above pins lead to increased connection resistance to impact and vibration. It is easier to install or separate the grooved beads than other locking beads.
