When it comes to heavy-duty fastening in high-pressure and high-temperature environments, not all nuts are created equal. Enter the ASTM A194 grade 2H nut—a powerhouse in the world of industrial fasteners. If you’re in the oil, gas, or petrochemical industries, chances are you’re familiar with the critical role these nuts play in keeping operations secure and reliable. But what exactly makes 2H nuts so special, and where can you find a trusted supplier? Let’s dive into the details.

What Are 2H Nuts?

ASTM A194 grade 2H nuts are a type of heavy hex nut that meets the stringent ASTM A194 specification. This specification is issued by the American Society for Testing and Materials (ASTM) and covers carbon steel, alloy steel, and stainless steel nuts used in high-pressure and high-temperature service.

Breaking Down the Grade:

• ASTM A194: The overall specification ensuring that these nuts can handle the intense demands of high-pressure and high-temperature environments.
• Grade 2H: This grade is a specific classification within the ASTM A194 standard. Made from medium-carbon steel that has been quenched and tempered, Grade 2H nuts are known for their incredible strength and durability. They’re designed to withstand the most extreme conditions, making them a top choice for critical bolting applications.
• Heavy Hex Design: The "heavy hex" design refers to the nut's shape and dimensions. Compared to standard hex nuts, heavy hex nuts are thicker and have larger dimensions across the flats. This design not only provides greater strength but also allows for better wrenching and a more secure fit.

Applications: Where Strength Meets Reliability

ASTM A194 grade 2H nuts are the go-to choice in industries where failure is not an option. These nuts are commonly used in:

• Flanges
• Fittings
• Valves
• Pressure vessels

Their ability to handle the intense pressures and temperatures found in oil, gas, and petrochemical applications makes them indispensable in maintaining the integrity of critical infrastructure.
