Recently, Ningbo Mohai Fasteners Co., Ltd. has launched a series of high-end fastener products covering multiple scenarios and full specifications, leveraging years of technical accumulation and innovative breakthroughs. The product range includes core categories such as Grade 8.8-12.9 high-strength bolts, customized hexagon studs, and precision hexagon nuts. With the product advantages of "high adaptability, high reliability, and high durability", the company has successfully emerged as a high-end fastener supplier both domestically and internationally, providing core connection solutions for key fields such as machinery manufacturing, new energy, and rail transit.
As a modern high-tech enterprise deeply rooted in the fastener industry, Mohai Fasteners has always regarded technological innovation as its core competitiveness. Taking advantage of the industrial cluster resources in Yongnian District, Handan City, Hebei Province—the "Hometown of Fasteners in China"—the company has built a full-industry-chain layout integrating raw material R&D, product design, precision manufacturing, and finished product inspection. To meet the personalized needs of different industries, the company has established a professional R&D team that conducts special technical research targeting connection pain points under complex working conditions, achieving multiple breakthroughs in material formulas, structural design, and process optimization.
In terms of product matrix construction, Mohai Fasteners has formed a full-series product system covering both general scenarios and special requirements. Among them, the Grade 10.9-12.9 ultra-high-strength bolts are made of special alloy materials and processed through advanced technologies such as isothermal quenching and precision rolling . With a yield strength of over 940MPa and a tensile strength exceeding 1220MPa, these bolts are suitable for scenarios requiring extremely high connection strength, such as new energy vehicle chassis, large construction machinery, and aerospace supporting equipment. Thanks to their excellent fatigue resistance and impact resistance, they have become the preferred products in the high-end equipment manufacturing field.
To address customized demands, the company's non-standard hexagon stud series offers flexible customization from M3 to M56 specifications and 5mm to 300mm lengths based on customer drawings. It supports multiple material options including carbon steel, stainless steel, and alloy steel, and provides surface treatment processes such as galvanizing, nickel plating, and dacromet coating , adapting to special environments like high temperature, high humidity, and strong corrosion. The supporting precision hexagon nuts adopt high-precision thread processing technology, with thread tolerance controlled within ±0.01mm, forming a perfect fit with bolt products to effectively enhance the stability of connection structures. They are widely used in power equipment, rail transit, precision instruments, and other fields.
Quality control is the core advantage of Mohai Fasteners. The company has established a quality management system compliant with both ISO9001 and IATF16949 (formerly ISO/TS16949) standards , equipped with more than 20 sets of internationally advanced production and testing equipment, including imported cold heading machines from Germany, fully automatic heat treatment production lines, laser dimension measuring instruments, and salt spray test chambers. It realizes full-process visual control from raw material entry, production process monitoring to finished product delivery. Each batch of products undergoes 12 rigorous inspections such as tensile testing, hardness testing, and corrosion resistance testing, ensuring a 100% qualification rate for ex-factory products and product performance reaching the advanced level of international counterparts.
With superior product quality and professional technical services, Mohai Fasteners' customer network has covered more than 50 countries and regions around the world, establishing long-term strategic cooperative relationships with many well-known domestic and foreign equipment manufacturing enterprises and engineering construction groups. Its products have been successfully applied to major projects such as domestic high-speed rail construction, overseas wind power projects, and new energy battery production lines, winning high recognition from customers for their stable performance.
"Focusing on customer needs and creating ultimate products is the unchanging pursuit of Mohai Fasteners," said a company leader. He added that in the future, the company will continue to increase R&D investment, focus on layout in emerging fields such as new energy and high-end equipment manufacturing, and develop new lightweight, high-strength, and intelligent fastener products. Meanwhile, it will optimize the global supply chain service system to provide customers with integrated solutions from product design and customized production to after-sales technical support, helping the global industrial sector achieve higher-quality connections and development.
