Quantity
The Zhangzhou Nut Bolt is a high-performance fastening solution engineered for the demanding construction and maintenance of mining equipment. Manufactured in Zhangzhou, a key industrial hub in Fujian Province, this 1/2-inch bolting assembly combines ASTM A193 Grade B7 studs with ASTM A194 Grade 2H heavy hex nuts, delivering exceptional strength and reliability in the most challenging operational environments.
Technical Specifications
This fastening system is precision-engineered with a 13 UNC thread configuration, ensuring efficient installation and secure engagement. The material selection—A193 B7 chromium-molybdenum alloy steel for the bolt and A194 2H carbon steel for the nut—is a proven combination widely used in high-temperature and high-pressure service applications. Grade B7 offers a minimum tensile strength of 125 ksi for diameters up to 2-1/2 inches, while Grade 2H nuts provide the necessary proof load stress of 175 ksi, creating a balanced and reliable fastening pair.

Industry Standards and Compliance
Manufactured to API Specification 20E, the Zhangzhou Nut Bolt meets rigorous quality and technical requirements for bolting used in the petroleum and natural gas industries. This standard ensures strict supplier oversight, material traceability, and manufacturing consistency—critically important for mining operations where fastener failure can result in costly downtime and safety hazards. The tap-end stud design further enhances grip stability, minimizing the risk of loosening under heavy vibrations and dynamic loads common in mineral processing environments.
