Black Iron 2H Heavy Hex Nut DH Grade

SKU :

A Black Iron 2H Heavy Hex Nut is a specialized type of fastener that finds widespread usage across various industrial, construction, and engineering domains. Its unique design is engineered to withstand high loads and provide a secure and reliable connection. The "2H" grade is an indicator of its superior tensile strength, which results from the use of heat-treated steel during its manufacture.

The "Heavy Hex" attribute refers to its larger size than a standard hex nut, which makes it ideal for heavy-duty applications that require enhanced load-bearing capacity. The Black Iron finish is a protective coating applied to its surface that serves to protect it from corrosion and other environmental damages.

These nuts are commonly employed in high-strength applications like bridges, buildings, machinery, and the oil and gas industry, where they secure pipelines and equipment. The Black Iron 2H Heavy Hex Nut is revered for its exceptional load-bearing capacity, durability, and longevity, making it a vital component in various industrial and construction settings.


Black Iron 2H Heavy Hex Nuts have several properties that make them desirable in industrial and construction applications. Some of these properties include:

  • High Tensile Strength: These nuts are made from heat-treated steel with a 2H grade, which indicates that they have superior tensile strength. This means that they can withstand high levels of force without breaking or deforming.
  • Enhanced Load-Bearing Capacity: The Heavy Hex design of these nuts gives them a larger surface area and thickness, allowing them to handle heavier loads. This makes them ideal for use in heavy-duty applications that require a secure and reliable connection.
  • Corrosion Resistance: These nuts have a Black Iron finish that acts as a protective coating against corrosion and other environmental factors. This helps to ensure that the nuts remain functional and reliable even in harsh environments.
  • Durability: Because these nuts are made from heat-treated steel, they are highly durable and long-lasting.
  • Reliability: The combination of high tensile strength, enhanced load-bearing capacity, corrosion resistance, and durability makes Black Iron 2H Heavy Hex Nuts a reliable and essential component in many industrial and construction applications. They are trusted to provide a secure and lasting connection in a wide range of settings.

 Black Iron 2H Heavy Hex Nuts are commonly used in structural applications, such as construction and engineering projects. Some of their uses in structural applications include:
  • Bridges: These nuts are often used to secure the components of bridges, which must be able to withstand heavy loads and exposure to the elements. Black Iron 2H Heavy Hex Nuts are well-suited to this application because of their high tensile strength and corrosion resistance.

  • Buildings: In the construction of steel buildings, such as high-rise structures, these nuts are used to secure the steel beams and columns that form the building's structural frame. Again, the nuts' high tensile strength and load-bearing capacity make them well-suited to this application.

  • Machinery: Black Iron 2H Heavy Hex Nuts are also commonly used in the construction of heavy machinery, where they are used to secure various components. The nuts' ability to withstand heavy loads makes them ideal for use in this application.

In all of these applications, Black Iron 2H Heavy Hex Nuts are essential components of the structural framework. Their high tensile strength, load-bearing capacity, and durability ensure that they provide a long-lasting and reliable connection.
