The advantages of torsion shear type high-strength bolts are that the large hexagonal bolts have a simple large structure and the required construction space is small. The plum head can be directly unscrewed with an electric wrench, which is safe, simple and fast. It is very convenient to check the construction quality without the need for special personnel or equipment. Only general visual inspection can confirm that the plum head has been unscrewed to ensure the construction quality of the torsion shear type high-strength bolts.Torsion shear type high strength bolts are mainly used in industrial and civil buildings, railway bridges, highway bridges, pipeline bridges, tower mast structures, boiler racks, boiler steel structure construction, large-span industrial plants, high-rise civil buildings, various towers, light steel structures, lifting machinery and other buildings connected with steel structures. High strength: Torsion shear type high-strength bolts are usually made of high-strength alloy steel, which has strong compressive, shear and tensile strength, so they are widely used in various engineering fields. 2. Easy installation: Torsion shear type high-strength bolts are easy to install, do not require any pipe installation tools, and can be installed quickly. 3. Good anti-loosening performance: During the connection process, the self-locking property of the nut and the elastic deformation of the washer can effectively prevent the loosening of the bolts and ensure the firmness of the connection. 4. Not easy to corrode: The surface of the torsion shear type high-strength bolt is treated with anti-corrosion, which can resist the influence of natural environmental factors such as weathering and corrosion for a long time.
