In the contemporary industrial landscape, the Metal U-Bolt serves as more than a simple fastener; it is a critical engineering component ensuring the structural integrity of piping systems, automotive chassis, and renewable energy frameworks. As global enterprises navigate the complexities of supply chain resilience, the demand for Wholesale Metal U Bolt Factories that offer both scale and precision has reached an unprecedented peak. Our role as a leading manufacturer involves bridging the gap between raw metallurgical science and high-frequency industrial application.
Leveraging CNC automation and cold-forging technologies to ensure thread accuracy and tensile consistency across million-unit batches.
From Grade 304/316 Stainless Steel to high-strength Carbon Steel with Hot-Dip Galvanization, we match materials to environmental stressors.
Streamlined logistics and compliance frameworks tailored for EU, North American, and Southeast Asian industrial standards.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999 and is located at the Oujiang Port in Wenzhou City. It has complete production, processing, grinding and other departments. We mainly engage in the integrated manufacturing and sales of various electrical switches, shafts, plastic products, and hardware components.

Procuring metal U-bolts at a wholesale level requires a deep understanding of international regulatory frameworks. Our factory ensures that every batch produced complies with the RoHS Directive and REACH Regulations, which are critical for our European partners. For the North American market, we adhere to ASTM and ASME standards, ensuring that our tensile strengths and thread pitches meet the rigorous demands of US industrial safety codes.
We provide comprehensive documentation including MTRs (Material Test Reports), plating thickness certifications, and salt spray test results for maritime applications. This level of transparency is why Zhejiang Jifeilong is trusted by global Fortune 500 companies.
A: Beyond cost-efficiency, China's mature supply chain ecosystems allow for rapid scaling and integration of secondary processes like heat treatment and specialized coating within a single industrial hub.
A: We recommend using 316 Stainless Steel or Hot-Dip Galvanized Carbon Steel with a minimum coating thickness of 50-80 microns to prevent oxidization.
A: Yes, our OEM/ODM services include custom bending radii, leg lengths, and thread profiles based on your technical drawings.
A: For standard specifications, we maintain a rolling inventory. Custom bulk orders typically have a lead time of 15-25 days depending on the complexity.
