High Tensile B7 Bolts

Tensile B7 bolts are high-strength fasteners widely used in various industrial applications, particularly in the construction and manufacturing sectors. These bolts are made from a specific grade of steel known as AISI 4140, which offers exceptional tensile strength and durability. The "B7" designation refers to a specific ASTM A193 standard that sets the requirements for the chemical composition, heat treatment, and mechanical properties of these bolts.


Grade B7 bolts are often used in applications where a reliable and robust connection is essential, such as in the construction of bridges, buildings, and heavy machinery. B7 bolts are heat-treated alloy steel bolts suitable for high-stress, high-temperature applications, while B8 bolts are stainless steel bolts designed for superior corrosion resistance in environments where rust prevention is critical.
