In the complex architecture of modern mechanical assembly, the Butterfly Nut (often referred to as a wing nut) represents a critical intersection of accessibility and utility. As a leading China Butterfly Nut and Bolt Supplier & Exporter, we observe that the global market is shifting toward high-specification material requirements and rapid supply chain modularity.
The butterfly nut is uniquely distinguished by its two metal "wings," allowing for tool-free manual tightening and loosening. This design is paramount in applications requiring frequent adjustment, such as drum hardware, lighting rigs, and marine maintenance. Our role as an exporter is to bridge the gap between high-precision Chinese manufacturing and the rigorous quality standards demanded by international markets (DIN 315, ASME/ANSI standards).
We are transitioning from standard carbon steel to advanced alloys including 316L Stainless Steel, Titanium Grade 5, and specialized nickel-based superalloys for corrosive environments.
Advanced hot-dip galvanizing and PTFE coating processes are now standard in our production line, ensuring long-term structural integrity in maritime applications.
Implementation of AI-driven hash detection and automated optical sorting ensures a defect rate approaching zero, adhering to our stringent sampling inspection systems.
Exporting fasteners is not merely about logistics; it is about compliance. Whether it is REACH compliance for European distribution, RoHS for electronics, or specific Classification Society certifications for marine engineering, our team manages the complex regulatory landscape. We provide full Material Test Reports (MTRs) and traceability documentation, ensuring your supply chain remains transparent and audit-ready.
Unlike generic producers, we utilize cold-forging and high-precision CNC finishing to ensure wing durability and thread tolerance accuracy, reducing assembly failure rates.
Yes. As a direct factory supplier, we specialize in non-standard butterfly bolt dimensions, thread pitches, and specialized plating options tailored to your engineering specifications.
Our group holds over 100 utility model patents and eight invention patents, driving innovation in fastening technology.
We manage 100,000+ product models, with 500 tons of raw materials and 10,000 tons of finished goods in stock.
Established in 2015, we are leaders in special fasteners and ultra-high precision components for global industry.
