bolt
Bolts, common fasteners, are indispensable in industrial production, construction, machinery manufacturing, etc. Structured with heads (hex, hex socket, round, square, etc.) and shanks (with external threads), they fasten parts by matching nuts or screwing into internally - threaded components, widely used for simple structure, reliable connection and easy disassembly.
shishi-nut
nut
Nuts, working with bolts via thread fit, tightly connect components. Their internal thread specs like size and pitch follow strict standards, requiring precision machining and inspection for perfect matching. Structured as hollow cylinders or hexagons with internal threads matching bolts, they fasten parts using friction and axial force.

Our Advantages
Technology R&D and innovation strength
We have a professional R&D team, equipped with advanced simulation software and precision testing equipment, dedicated to researching the material properties and forming processes of fasteners. We can develop customized solutions for the needs of different industries (such as high-strength and corrosion-resistant scenarios), break through the limitations of traditional processes, and achieve product performance upgrading.
Product quality and reliability
A full-process quality control system has been established, covering strict selection of raw materials (compliant materials + traceability management) and real-time monitoring of all production links. It is equipped with high-precision testing instruments (such as tensile testing machines and spectrometers). The product performance is stable and can maintain reliable performance even under extreme working conditions.
Customer resources and market share
We have accumulated numerous benchmark clients in industries such as large machinery manufacturers and infrastructure enterprises, with long-term cooperation lasting over 5 years and a repeat purchase rate of more than 60%. A rapid response service system has been established to connect with customer needs within 24 hours and provide full-process technical support.
Product Lines and Solutions
We have multiple automated production lines with an annual output capacity of over 10 million pieces, enabling rapid switching to produce different types of fasteners. Leveraging our technical accumulation, we provide full-process solutions from customized drawings and sample trial production to mass production, shortening the production and delivery cycle.
