High Strength Combination Bolt

High Strength Combination Bolt

High strength combination bolt is designed specifically for the occasions of highways, high-speed rails and other high-strength and high-quality requirements. Bolt shear and wall are used to transmit pressure in ordinary bolt, so pretension is small. In this series of product, apart from the high strength of the material itself, pretension is very large so extrusion pressure is generated between the connecting parts, thus increasing the frictional force perpendicular to the screw direction and overall integrity and rigidity. We can manufacture products according to different specifications for highways to meet customers’ needs.
