API 20E BSL-1 fasteners are designed for non-critical applications where standard strength and safety are required. These fasteners provide cost-effective solutions for projects where the operational environment is less demanding but still requires compliance with industry standards.

The API 20E BSL-2 fasteners are intended for more demanding applications where moderate strength and safety are necessary. These fasteners undergo more stringent testing and quality control, ensuring that they meet the needs of industrial projects with moderate operational stress.

BSL-3 fasteners are the highest specification bolts and nuts, used in critical and high-stress environments. These fasteners undergo rigorous testing and certification to ensure superior durability, making them ideal for subsea applications, offshore platforms, and other high-risk industrial environments.

ASTM A193 Grade B7 studs are made from alloy steel and are designed for high-temperature, high-pressure applications. They are commonly used in flanges, pressure vessels, and other high-stress industrial components, offering excellent strength and heat resistance.

ASTM A194 Grade 2H nuts are heavy-duty, heat-treated nuts used in combination with B7 studs. These carbon steel nuts are suitable for high-pressure and high-temperature applications, providing reliable strength in critical installations.

In addition to standard options, Dashna offers a range of specialized alloy and stainless steel fasteners for corrosion-resistant and high-performance applications. These fasteners are used in industries where long-term durability and resistance to harsh environmental conditions are essential.
