A325 fasteners are heavy hex structural bolts that conform to the specifications set forth by the American Society for Testing and Materials (ASTM). These fasteners are primarily used in conjunction with A325 nuts and are designed to create bolted connections in steel structures, providing robust and durable performance under various loads and environmental conditions.

In modern engineering, double end studs find applications across several fields. In the automotive industry, they are used to secure engine components, ensuring that parts remain tightly fastened despite vibration and movement. In the realm of civil engineering, double end studs are prevalent in structural applications, such as steel beam connections, where strength and reliability are paramount. The oil and gas industry also relies heavily on double end studs in pipeline construction and maintenance, where the need for secure and leak-proof connections is critical.

- Outdoor Applications They can be used for installing fences, poles, and outdoor furniture, providing the necessary strength and durability against the elements.
