Product Functionality and Key Features

The A193-B7/A194-2H black stud bolts are designed for demanding environments where corrosion resistance and mechanical strength are critical. These fasteners are fully threaded, meaning they feature continuous threads along their entire length, which enhances their load-bearing capacity and ease of installation. The black finish is achieved through a specialized coating process that improves durability in harsh conditions.

One of the standout features of these bolts is their compliance with ASTM A193 and ASME B16.5 standards, ensuring they meet the rigorous requirements of high-pressure and high-temperature applications. This makes them ideal for use in critical industries such as oil and gas, power generation, and chemical processing.
