Hex Bolts: Applications and Advantages

Hex bolts are widely used across various industries and products due to their simple design, high strength, and ease of installation. Below are some key applications and advantages of hex bolts:

Industries and Products That Use Hex Bolts

1. Construction Industry
- Hex bolts are commonly used in structural steel connections, such as bridges, building frameworks, and scaffolding. Their ability to handle heavy loads and external forces like wind ensures stability and durability in construction projects.

2. Machinery Manufacturing
- In machinery and equipment assembly, hex bolts are essential for fastening mechanical parts in machinery such as lathes, heavy-duty equipment, and assembly lines. Their high strength and durability make them suitable for machines operating under vibration and heavy loads.

3. Automotive and Transportation
- Hex bolts are widely used in the automotive industry for securing critical parts like chassis, engines, and transmission systems. Their strength and reliability help maintain the vehicle's integrity under high-speed and heavy-duty conditions.

4. Home Appliances and Electronics
- Hex bolts are used to assemble and secure parts in appliances such as air conditioners, washing machines, and televisions. They provide reliable connections and ensure the overall stability of the products.

5. Energy and Petrochemical Industry
- Hex bolts are crucial in wind turbines, nuclear power plants, and petrochemical plants, where they are used in securing large equipment and pipeline systems. Their corrosion resistance and strength allow them to perform in harsh environments.

6. Marine and Offshore Engineering
- In shipbuilding and offshore platforms, hex bolts are used to secure deck fittings, hulls, and equipment. Stainless steel hex bolts, in particular, resist corrosion from seawater, ensuring the longevity of marine structures.

7. Furniture Manufacturing
-Hex bolts are frequently used in the assembly of furniture such as beds, tables, chairs, and cabinets. Their easy installation and firm fastening provide stability and long-term durability to household and office furniture.

Applications

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218 per cent to 2.11 per cent. It is also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.

Classification
(1) According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free-cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two;
(2) According to the smelting method can be divided into flat furnace steel, converter steel;
(3) According to the method of deoxidation can be divided into boiling steel (F), sedentary steel (Z), semi-sedentary steel (b) and special sedentary steel (TZ);
(4) According to the carbon content of carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC ≥ 0.6%);
(5) According to the quality of steel can be divided into ordinary carbon steel (containing phosphorus, sulphur higher), high-quality carbon steel (containing phosphorus, sulphur lower) and high-quality steel (containing phosphorus, sulphur lower) and high-quality steel.

Low carbon steel - carbon content is generally less than 0.25 per cent; medium carbon steel - carbon content is generally between 0.25 and 0.60 per cent; high carbon steel - carbon content is generally greater than 0.60 per cent. Steel contains carbon (C) elements and for deoxidation and contains a certain amount of silicon (Si) (generally not more than 0.40%), manganese (Mn) (generally not more than 0.80%, higher can be up to 1.20%) alloying elements, does not contain other alloying elements (except for residual elements).

Black oxidation treatment is a common means of chemical surface treatment, the principle is to produce a layer of oxide film on the surface of the metal, in order to isolate the air, to achieve the purpose of rust prevention. Appearance requirements are not high when you can use the blackening treatment, the surface of steel parts blackening treatment, there are also called blue. Black oxidation treatment, because it can eliminate reflections, refers to a surface coating treatment commonly used for military knives
