Carbon Steel Hex Bolts are commonly used in a variety of applications, including construction, automotive, and machinery industries. These bolts are made from carbon steel, which is a type of steel that has a high carbon content. Carbon steel is known for its strength, durability, and resistance to corrosion.

There are several different types of carbon steel hex bolts, including:

1. Grade 2 - This is a low carbon steel that is commonly used in general construction applications. It has a tensile strength of 60 ksi and a yield strength of 36 ksi.

2. Grade 5 - This is a medium carbon steel that is commonly used in automotive and machinery applications. It has a tensile strength of 120 ksi and a yield strength of 105 ksi.

3. Grade 8 - This is a high carbon steel that is commonly used in heavy-duty applications, such as automotive and machinery applications. It has a tensile strength of 150 ksi and a yield strength of 130 ksi.

Carbon steel hex bolts are a reliable and cost-effective option for a wide range of applications. With their strength, durability, and resistance to corrosion, they are an excellent choice for any project that requires a strong and reliable fastener.
