Fasteners are important connecting parts in automobile, high-speed railway, airplane, ship, wind power and many other machinery and equipment.Its design, manufacturing, assembly, testing and other processes are complex.Once failure occurs, often cause the failure of the entire connection system or even the entire equipment, easy to cause a large safety accident.

Therefore, the use of fasteners requires strict design and experimental verification.Shanghai NG28 Zhike Material Technology Co., Ltd.  can provide one-stop bolt design, testing and verification services for the whole life cycle of bolts, to guarantee the safety of bolt connection.
