ASTM A194
ASTM A194 Grade 2H heavy hex nuts are high-strength fasteners manufactured from quenched and tempered medium-carbon steel, designed for high-pressure and high-temperature applications.
Engineered for reliability under extreme conditions, they’re commonly used with bolts such as ASTM A193 Grade B7 and in structural, petrochemical, and power generation projects. These nuts offer excellent hardness, tensile strength, and resistance to stress and heat.
Available in plain, zinc-plated, and hot-dip galvanized finishes, Grade 2H nuts provide secure, durable fastening performance in critical industrial environments.
