nut bolt

add to cart The Nut Bolt is a high-performance fastening solution engineered for the demanding construction and maintenance of mining equipment. es 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 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. Application Scenarios These fasteners are ideally suited for a wide range of mining applications: - Conveyor Systems: Securing structural frameworks and roller assemblies - Crushers: Fastening housings and wear components subjected to extreme impact forces - Grinding Mills: Anchoring liner bolts and heavy-duty components - Structural Supports: Bolting frameworks and gearboxes in high-load conditions The A193 B7/A194 2H material combination maintains mechanical properties at elevated temperatures up to 1000°F, making it reliable in both surface and underground mining operations where heat generation is significant.
