In the complex architecture of modern global industry, the role of Big Screws and heavy-duty fasteners cannot be overstated. As a premier OEM Big Screws Supplier, Ningbo Krui Hardware Product Co., Ltd. understands that these components are the literal binding agents of civilization—holding together bridges, industrial machinery, and large-scale architectural structures.
Founded in 2004, our facility in Ningbo utilizes advanced hot and cold forging, alongside CNC precision machining. We don't just supply screws; we supply engineering solutions that ensure structural integrity under extreme load conditions.
Strategically located 15 minutes from the Ningbo seaport, we have streamlined logistics to serve North America, Europe, and Asia. Our supply chain is optimized for the just-in-time delivery requirements of major global enterprises.
As an ISO 9001:2008 certified manufacturer, we adhere to strict international standards including DIN, ASTM, and JIS. Every component undergoes rigorous testing, ensuring it meets the safety requirements for critical applications.
The manufacturing landscape is shifting towards Industry 4.0. Our roadmap includes integrating IoT-enabled smart fasteners and advanced surface treatment technologies to prevent corrosion in marine and chemical environments. We are currently investing in:
A: Depending on the complexity and material, standard custom orders typically range from 30 to 45 days. We prioritize clear communication to ensure your project timelines are met.
A: Yes, we serve clients globally. We provide comprehensive export documentation and ensure all products comply with regional standards (e.g., REACH, RoHS, or specific DIN grades).
A: Absolutely. We specialize in non-standard metal components. Our R&D team reviews your technical drawings or physical samples to design a manufacturable, cost-effective solution.
A: We work with high-grade stainless steel (304/316L), carbon steel, alloy steel, aluminum, and brass, ensuring the right metallurgical properties for your specific application.
Our 55-person strong professional team operates from our Ningbo hub, combining human expertise with high-tech automated machinery.
Advanced hot forging capabilities for large, heavy-duty screws, ensuring superior grain flow and structural strength.
High-precision CNC Lathes (1, 2, and 3) ensure every thread, head, and dimension is accurate to the micron.
