Shanghai Huxi High Strength Bolts & Nuts Factory is a professional enterprise specializing in production of large-scale, long-type high strength bolts and nuts, which is suitable for thermal power, wind power, lifting, aerospace, shipbuilding, and engineering machinery industry. Founded in 1985, it is located at No. 9125, Fenggong Road, Chuannan, Hongmiao Town, Fengxian District, Shanghai and No.1085, Penggongtang, Liaoyuan, Fengxian. With the area of 42,000 square meters, we have over 300 employees. The company is with new production equipment and advanced detection equipment, and we have the annual production capacity of 800 million units. The products are widely used in electricity, lifting, aerospace, shipbuilding, engineering machinery. We can also produce set of high strength hexagon bolt, the torsion set of high strength bolts, ANSI and DIN high strength sets, GB, non-standard high strength bolts nuts. The technical accuracy has reached to international standards, and the intensity includes Grade 8.8, Grade 10.9, Grade 12.9, and Grade 14.9. Do well in the production: special long & thick high-strength bolts (diameter: m30-m220, length up to 16000mm) Characteristic Production: high strength bolts(Grade 10.9,Grade 8.8 ,diameter from m42 to m160, ultra-low temperature impact value :-50 ℃, AKV ≥ 60j anti-low temperature and anti-brittle broken high strength bolts). Technological Innovation: the factory has developed a special process to solve the problem of delaying high strength bolts’ fracture to ensure the provisions of high strength bolts accordance with the GB JB/T5057.40 or German standard DASt high strength bolt preload and tightening torque values once Tighten. It doesn’t loose automatically in 20 years, and doesn’t delayed fracture in 30 years. Quality Ensurance: There is no claims record of high strength bolts in the construction, installation, and operations nearly 20 years. With the advanced technology, pursuing no claims records in 30 to 60 years is our true target of high quality. Service Mission: The factory does not participate in intra-industry competition and we do not disturb those who have normal suppliers. We are willing to undertake orders that no one would like to take. (high quality, good service, and reasonable prices.)
