Application :
Hexagon bolts are widely used in building engineering. In steel structure buildings, they are used to connect main components such as steel beams and columns to ensure the stability and safety of building structures. Bridge construction, connecting all parts of the bridge, such as bridge deck, box girder, pier, etc., bears the weight and dynamic load of vehicles and bridges themselves. Mechanical equipment, such as large machine tools, cranes, mining machinery, etc., is used to fasten key components and ensure the stability and reliability of the equipment in operation. Energy field, railway transportation, shipbuilding, power facilities: such as installation and fixation of telephone poles, transformers and other equipment.
