B7 Bolts
High Tensile ASTM A193 B7 Bolts
ASTM A193 Grade B7 bolts are one of the most widely used high-strength fasteners for pressure vessels, flanges, valves and industrial pipework. Manufactured from heat-treated chromium-molybdenum alloy steel, B7 bolts offer excellent tensile strength and are designed for high-temperature and high-pressure applications.
Their outstanding mechanical properties make them suitable for demanding environments across oil and gas, petrochemical, energy generation and heavy engineering.
