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:

1, 321H belongs to the American Standard austenitic heat-resistant steel forgings, the implementation of the standard: ASTM A959-2011

321H is a titanium-stabilised austenitic stainless steel with good overall corrosion resistance.It has excellent resistance to intergranular corrosion at temperatures exposed to carbon carbide precipitation in the range of 800-1500°F (427-816°C).The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L.It also has good low temperature toughness.

2, 304: is a common material in stainless steel, density 7.93 g/cm3, the market common labelling methods in 06Cr19Ni10, SUS304.

Two characteristics are different

1, 321: with excellent high temperature stress break (Stress Rupture) performance and high temperature resistance to latent change performance (Creep Resistance) stress mechanical properties are better than 304 stainless steel.

2, 304: 304 in the most important elements are Ni, Cr, but not limited to these two elements.Specific requirements specified by the product standard.Industry common judgement that as long as the Ni content is greater than 8%, Cr content is greater than 18%, can be considered as 304 stainless steel.
