Ningyuan Fastener
In the complex ecosystem of industrial fasteners, Butterfly Nuts (Wing Nuts) and Bolts represent a critical intersection of ergonomic design and mechanical reliability. As a leading manufacturer based in Handan, the fastener capital of China, Handan Ningyuan Fastener Manufacturing Co., Ltd. (formerly Jin Langtao) has spent over two decades perfecting the metallurgical and structural integrity of these essential components.
Butterfly nuts are uniquely engineered for applications requiring frequent, manual adjustments without the need for specialized tools. This "tool-less" advantage makes them indispensable in sectors ranging from photovoltaic (PV) mounting systems to aerospace interior assembly and precision medical equipment.
Modern engineering demands speed. Butterfly fasteners provide the "Information Gain" in assembly logisticsโreducing downtime during maintenance and allowing for rapid prototyping in R&D environments.
We manufacture according to international standards including DIN 315, ASME B18.6.X, and custom OEM specifications. Materials include Stainless Steel (304/316), Carbon Steel with Zinc Flake coating, and specialized High-Performance Nylon.
Through advanced Hot-Dip Galvanizing and Electrophoretic coating, our bolts withstand 1000+ hours of salt spray testing, exceeding industrial norms for outdoor seismic and PV systems.
The global demand for Butterfly Nuts and Bolts is currently driven by the surge in Renewable Energy Infrastructure. In North America and Europe, the shift towards decentralized power grids requires millions of robust, easy-to-maintain fastening points for solar trackers and wind turbine sensors. Our factory bridges the gap between high-volume production and surgical precision.
As integrated into our Pipe Gallery Support Systems and Seismic Support Arms, our butterfly bolts ensure structural stability during seismic events. By utilizing energy-dissipation designs, these fasteners prevent catastrophic loosening under high-frequency vibration.
Ningyuan's photovoltaic accessories, including C-shaped steel and hot-dip galvanized triangle bases, utilize our specialized bolt series to offer a 25-year service life, matching the lifespan of high-efficiency solar modules.
The fastener industry is moving toward "Smart Fastening." Our R&D department is currently exploring:
Handan Ningyuan Fastener Manufacturing Co., Ltd., founded in 2005, is located in Handan Yongnian, the hometown of Taiji and the fastener capital. Since its inception, the company has adhered to the enterprise philosophy that "Development is the Direction and Hard Work is the Truth."
Through 18 years of wind and rain, we have formed a research and development department as the basis, production department as the center, and sales department as a breakthrough. Our service content covers high-end fastener standard parts, including photovoltaic new energy systems, building electromechanical seismic systems, and more.
Navigating international trade requires more than just a product; it requires a partner who understands regulatory ecosystems.
Our facility is ISO9001 certified. We provide full traceability for every batch, including ROHS EU testing, GB/T30512 automotive banned substances, and 2000/53/EC ELV testing compliance.
With an annual output of 60 million+ pieces, we offer rapid delivery cycles. We support Free Samples for regular products and provide professional technical installation guidance for custom projects.
Our 6 senior technicians provide free fastener solution rate analysis, ensuring you choose the right butterfly nut material for your specific environmental humidity and mechanical load.
A1: The primary advantage is the "Butterfly" or "Wing" design which provides leverage for hand-tightening. This is ideal for applications requiring frequent disassembly, such as drum sets, lighting rigs, or temporary PV panels, where tools are inconvenient or unavailable.
A2: We recommend Hot-Dip Galvanized Carbon Steel or 316 Stainless Steel. These materials provide the necessary tensile strength and cathodic protection required to endure variable weather conditions and structural vibrations.
A3: Yes. With over 50 sets of advanced production equipment and 25+ patents, we can manufacture custom wing shapes, thread pitches, and specialized coatings tailored to your specific industrial requirement.
A4: We utilize precision threading and can provide wing nuts with integrated locking features or specialized washers that increase friction, ensuring that the manual tightness achieved by hand remains secure under load.
Whether you are designing a new solar array or reinforcing a skyscraper, Ningyuan's Butterfly Nuts and Bolts provide the reliability you can trust. Let our experience be your growth engine.
