ZZHJ Aerospace Precision Technology Corporation is committed to the research, development and production of aerospace high-end fasteners and precision components.
The products are mainly used in civil aerospace and aviation.
ZZHJ can greatly improve the durability of self-locking nuts, reduce the number of nuts, and thus reduce the weight of the engine.
The company has established an advanced fastening and connection technology center&advanced fastening and connection technology laboratory. The company is an invisible champion in the field of fasteners in the aviation and aerospace fields.
The company's products have been certified by the French BV Group AS9100D International Aerospace Quality System.
The company's "Research and Industrialization of Key Technologies for Shape Control of High-strength Self-locking Nuts for Aero-engines" project won many invention awards.
The project reduces the attenuation of self-locking nut locking performance from 50% to 35%, reduces the number of engine nuts used, and improves the performance of the aircraft by studying the influence of the life cycle of the lifting nut and the closing process factors on the self-locking nut locking performance.
