The industry is based on connections. Connections play an important and key role in every industry. This role affects the desired industry either directly or indirectly. Connections include two types of permanent connections and temporary connections. As temporary connection tools, bolts and nuts are one of the most practical industrial tools. They play a role in all the industries around us, so they have wide and varied applications. The use in different industries has led to the design of various types of industrial bolts and nuts. What is meant by the types of bolts and nuts is its variety in model, material and size. Each type of bolt has special features and is used in a specific application. Jahan Pich Sanat is a supplier of all kinds of industrial bolts and nuts in the highest quality and made according to the latest international standards.
Types of Industrial Bolts
Hex bolts and nuts
Hex bolts and nuts are the most widely used types of bolts and nuts. Hex screws are screws with a hexagonal head and a cylindrical, threaded body. Hex screws are also called wrench screws because wrenches are used to open and close these screws. A hex nut is a nut with a hexagonal body and a threaded hole that is used to tighten many connections. Hex bolts and nuts are produced in regular and heavy duty (HV) models. Heavy hex bolts and nuts are used in applications that require high strength and weight bearing. Due to the wide use of these bolts and nuts in different industries, they are made of different materials. The most common types of hex bolts and nuts are made of plain carbon steel, iron, stainless steel, galvanized steel, and iron and black work steel. Also, this screw and nut, like other connections, are produced in different dimensions.
Allen screw
Its screw is a type of screw with different models of head and It has a socket hole. This type of screw has a threaded body like other screws. The difference between Allen screw and ordinary screws is in opening and closing it. Since the hole or groove of the Allen screw head is a socket, special wrenches called wrenches or Allen keys are used to open and close this screw. This wrench is placed inside the screw socket and by turning it, it opens and closes the screw. Therefore, this screw is very suitable for use in applications where the gap is tight. Allen screw has different types based on its appearance. Each of these screws has special features. The types of Allen screws include nut Allen screws, cylindrical Allen screws, shoulder Allen screws, and shoulder Allen screws. Allen screw is one of the most widely used types of industrial screws and nuts. They are specifically used in the automotive industry, manufacturing and assembly of industrial machines and devices, building construction, various structures, power plant construction, etc. Allen screws are produced and supplied in different materials and sizes. Steel, steel, galvanized and plastic Allen screws are the most widely used types of Allen screws.
Iron screw
Ahi screw refers to different types of screws that are made of iron. In fact, this category of bolts and nuts refers to their type. In the past centuries, iron screws were the most widely used type of screws and nuts. But with the introduction of steel screws, their use decreased, especially for applications that require high mechanical properties. But it is always used for normal applications where the connection is not under force and tension, as well as humidity and corrosive environments. Because it has a lower price than other types of metal screws. Iron screws have poor corrosion resistance, therefore, for applications where corrosion resistance is important, they are galvanized or coated with black and dachromate.
Bolt master< /b>
Bolt master is another type of connection tools or screws that has many industrial applications. This tool is a threaded cylinder, or we can say that Master Bolt is a headless screw. Master bolts are usually a bridge between two parts or two parts of one part, which have a nut on both sides and tighten the connection. The most important application of Ostad Bolt is in the piping industry of oil, gas and petrochemical industry. Master bolts are produced in different dimensions. Also, they are diverse in terms of materials. The most widely used type of master bolts are galvanized and steel master bolts. Because, as we said, their use is mostly in petrochemicals and they are related to chemicals and corrosive substances, so corrosion resistance is one of the most important characteristics for this type of screw.
Roll bolt
Roll bolt is one of the types of connection tools that are used to create connections in materials such as cement, concrete, plaster, stone, etc. Therefore, roll bolts are widely used in the construction industry and the construction of various structures such as bridges, tunnels, power plants, etc. Roll bolts have different types based on their design. But usually they consist of four general parts. A screw, a nut, a washer and a grooved hollow cylinder are the four components of this tool. To connect the roll bolts, you must first make a hole in the place and insert the grooved cylinder into the hole. Then we insert the roll bolt screw and finally insert other connecting components and close the nut and washer on it. Roll bolts are usually made of galvanized steel or steel. In addition to having good mechanical properties, they also have high resistance to corrosion and rust. Metric screw Metric screw is a type of screws. It is threaded as a long rod. In fact, metric screws are long and threaded rods that are cut to the size desired by the customer. This type of screw is one of the headless screws and is used to connect two parts or two parts to each other. The metric screw is used in various applications such as construction, structures, oil, gas and petrochemical industries, etc. Metric screw is available in different thread diameters and dimensions, and its length is also cut according to your needs. These screws are available in different materials such as plain carbon steel, galvanized steel, stainless steel (steel). According to the needs of your application, buy this bag in the right size and material.
