Ningbo Zhongli Bolts’Successful Exhibition Debut at Fastener Expo Shanghai 2026

From June 24 to June 26, 2026, Fastener Expo Shanghai, one of the most influential professional fastener exhibitions in Asia, grandly opened in Shanghai. As a professional high-strength fastener manufacturer with more than 20 years of production experience, Ningbo Zhongli Bolts Manufacturing Co., Ltd. made a stunning appearance at the exhibition, showcasing its core products, innovative patented technologies and customized manufacturing capabilities, attracting numerous domestic and foreign merchants, industry experts and purchasers to stop for consultation and in-depth cooperation discussions.

Founded in 2003, Ningbo Zhongli Bolts has always focused on the research, development, production and sales of high-precision and high-strength fasteners. After two decades of steady development, the company has grown into an innovative and technology-oriented enterprise integrating standardized mass production and personalized customized processing, serving global industrial manufacturing fields with reliable product quality and professional service system. Adhering to the production concept of “Precision Manufacturing, Quality First”, the company has built a complete industrial production system, introduced fully automated production equipment and high-precision testing instruments, and implemented strict quality control standards in every link from raw material selection, precision processing to finished product inspection, ensuring that every batch of products meets international and national industry specifications.

At this Shanghai exhibition, Zhongli Bolts displayed a full range of star products covering multiple international standards, fully demonstrating the company’s comprehensive product strength and market adaptability. The exhibited products include national standard series such as GB5782, GB5783 coarse thread full-thread bolts, GB5785, GB5786 fine thread hex bolts and GB5787 flange face bolts, as well as German standard mainstream products including DIN931, DIN933 full-thread and half-thread hex bolts and DIN6914 series products. In addition, the company’s self-developed patented product—the anti-loosening buffer hex bolt became the highlight of the exhibition. This patented technology effectively solves the common problems of bolt loosening, vibration damage and fracture risk in industrial operation, greatly improves the stability and service life of mechanical connection structures, and fills the technical gap of high-durability fasteners in some application scenarios, winning high recognition from professional audiences.

In terms of product performance and quality positioning, Zhongli Bolts focuses on high-strength fastener manufacturing, with core products covering 10.9-grade and 12.9-grade high-strength carbon steel bolts. The products are made of high-quality 40Cr carbon steel materials, and undergo professional blackening and galvanizing anti-corrosion treatment processes. They have excellent characteristics such as high tensile strength, strong wear resistance, anti-corrosion and anti-fatigue, and can adapt to harsh working environments such as high temperature, high pressure and strong vibration. The company not only provides standardized conventional products with complete specifications and sufficient inventory, but also supports non-standard customized processing according to customers’ drawings and samples, flexibly meeting the personalized connection needs of engineering machinery, steel structure, automobile manufacturing, mechanical equipment and other industries.

With reliable product quality and flexible service advantages, Zhongli Bolts' products are not only widely sold in domestic markets across China, but also exported to Europe, America, the Middle East, Southeast Asia and other global regions, establishing long-term stable cooperative relations with numerous well-known manufacturing enterprises. During the three-day exhibition, the company’s professional sales and technical teams communicated face-to-face with visiting customers, systematically displayed product parameters, technical advantages, production capacity and after-sales service system, and provided targeted product matching and solution suggestions according to customers’ different application scenarios and procurement demands. The on-site professional and efficient service attitude, together with the excellent quality display of physical products, won unanimous praise from new and old customers.

This participation in the Shanghai Fastener Expo is not only a comprehensive display of Zhongli Bolts’ technical strength and product advantages, but also an important opportunity for the company to deepen industry exchanges, expand global markets and grasp the latest industry trends. In the fastener industry with increasingly fierce market competition and continuously upgraded technical requirements, product reliability and technological innovation have become the core competitiveness of enterprise development.

In the future, Ningbo Zhongli Bolts Manufacturing Co., Ltd. will continue to take technological innovation as the driving force, continuously optimize production processes, upgrade product quality, enrich product categories, and further improve customized service capabilities and global supply chain service levels. The company will always adhere to the customer-centric concept, focus on solving the connection pain points of industrial manufacturing, provide more high-quality, high-precision and high-reliability fastener products for global customers, and strive to become a trusted long-term cooperative partner in the global fastener industry, contributing steady strength to the high-quality development of the industrial manufacturing industry.
