Coburn-Myers proudly supplies 2H nuts, a trusted solution for high-strength, high-pressure, and high-temperature applications across a variety of industries. With a commitment to quality and expertise, we ensure our 2H nuts meet the most stringent standards, making them ideal for critical environments.

What Are 2H Nuts?

2H nuts are heavy hex nuts designed for demanding industrial applications. These nuts are manufactured to meet the rigorous requirements of ASTM A194 Grade 2H standards, ensuring they can withstand extreme pressure, temperature, and mechanical stress. Their unique heavy hex design provides more surface area for wrenching and higher torque capacity compared to standard hex nuts, making them a reliable choice for mission-critical applications.

Applications of 2H Nuts

2H nuts are indispensable in industries where safety and performance are non-negotiable. Here are some of the key applications:

1. High-Pressure Systems

2H nuts are commonly used in pressure vessels, valves, and flanges. Industries such as oil and gas, chemical processing, and power generation rely on these nuts to maintain secure connections in high-pressure environments without the risk of deformation or failure.

2. High-Temperature Environments

Designed to handle elevated temperatures, 2H nuts are ideal for boilers, steam lines, and heat exchangers. The heat-treated steel composition ensures they retain their strength and integrity even under thermal stress.

3. Structural and Heavy-Duty Connections

For construction projects, bridges, and steel structures, 2H nuts provide the robust fastening needed for load-bearing connections. Their durability makes them a top choice for contractors and engineers alike.

4. Oil and Gas Industry

From pipeline systems to offshore platforms and refineries, 2H nuts excel in corrosive and high-stress environments, ensuring safety and efficiency in operations.

5. Industrial Machinery

Large-scale machinery and equipment depend on 2H nuts for secure and durable fastenings, particularly in heavy-duty industrial settings.

Material Composition and Manufacturing

The exceptional performance of 2H nuts stems from their carefully engineered materials and manufacturing processes. Here’s a closer look at what makes them unique:

1. Material Composition

• Medium Carbon Steel: Offers a balance of strength and ductility, making it ideal for industrial use.

• Alloy Steel: For applications requiring enhanced resistance to pressure and temperature, alloy steel variants are available.

2. Heat Treatment

2H nuts undergo quenching and tempering to increase tensile strength and hardness. This heat treatment process ensures they can withstand the extreme demands of high-stress applications.

3. Surface Finishes

• Black Oxide (Plain): Suitable for standard applications.

• Zinc Plating: Provides moderate corrosion resistance.

• Hot-Dip Galvanized: Offers enhanced protection against corrosion, ideal for outdoor and harsh environments.

• PTFE or Fluoropolymer Coatings: Used for chemical resistance and low-friction needs.
