Key Features and Advantages

1. Material Composition and Surface Treatment

The A193-B7/A194-2H black stud bolts are manufactured using high-grade carbon steel, meeting international standards for mechanical performance. The black finish is achieved through a combination of heat treatment and specialized coating processes, which not only enhances their visual appearance but also provides superior protection against oxidation and environmental degradation.

2. Structural Design

These fasteners feature a fully threaded design, with continuous threads running the entire length of the rod. This design ensures optimal load distribution and prevents stress concentration, making them suitable for applications requiring high tensile strength. The double stud bolt variant (A194-2H) offers additional mechanical stability for heavy-duty scenarios.

3. Corrosion Resistance

The black coating acts as a barrier against moisture and chemicals, significantly extending the service life of the bolts in corrosive environments. This makes them ideal for use in industries such as marine engineering, chemical processing, and outdoor construction.

4. Versatility

Available in multiple sizes and configurations, these bolts can be customized to meet specific project requirements. Their compatibility with standard nuts and fittings ensures seamless integration into existing systems.
