High Strength Bolts

High-strength bolts are made of high-strength or tempered alloy steel and are used where extremely high tensile strength is needed, such as bridges, rails, and high-pressure equipment. They are tightened or released by applying torque to a nut and are commonly used in structural bolting. The tensile materials used in these bolts tend to increase their strength by 25% to 50%. We manufacture the material from Property Class 3.6 to 12.9 with lengths up to 4 meters. The relevant accessories are also designed, manufactured, and supplied.
