This series of products are butterfly nuts (also known as thumb nuts, sheep horn nuts, hand-tightening nuts), which are convenient fasteners specially designed for scenarios requiring frequent disassembly and manual tightening. The products cover multiple materials and specifications such as stainless steel， carbon steel galvanized， and carbon steel blackened. They are manufactured through precise cold heading / stamping forming + high-precision tapping technology， featuring an integrated butterfly wing ear structure. Without the need for wrenches， sockets， etc., they can be quickly tightened or disassembled by hand， perfectly suitable for scenarios that require repeated disassembly and without the need for tools. They provide efficient and convenient connection and tightening solutions for home decoration， equipment maintenance， DIY handicrafts， and mechanical equipment fields.
Multiple material options, precise adaptation for all scenarios
The product covers three mainstream materials: 304 stainless steel, carbon steel galvanized, and carbon steel blackened. It precisely adapts to different working conditions:
304 stainless steel model: rust-resistant and corrosion-resistant, suitable for humid, outdoor, and food-grade scenarios, non-magnetic, non-toxic, and harmless
Carbon steel galvanized model: low cost, good rust resistance, suitable for ordinary home decoration, equipment maintenance, and general industrial scenarios
Carbon steel blackened model: high strength, wear-resistant, suitable for heavy load, mechanical, and appearance decoration scenarios
It can be flexibly selected according to the corrosive environment, load requirements, and appearance requirements.
Integrated butterfly-shaped wing ear structure, hand-tightening without tools, dual advantages
Strictly following the GB/T 62.1 (ISO 10675, DIN 315) international standards, the integrated butterfly-shaped wing ear structure has a large force-bearing area. By hand directly turning, it can complete tightening / disassembly without any tools, perfectly adapting to scenarios that require frequent disassembly and no tool operation; the wing ear shape is round, not scratching the workpiece and hands, operation is safe and convenient.
High-precision tapping process, tight engagement and uniform force
Using a fully automatic precision tapping process, the thread accuracy reaches 6H grade, with full tooth shape, no burrs, no slippage, and tight engagement with the same specification bolts. The force is uniform, the anti-loosening performance is excellent, it can withstand regular vibration loads, avoiding the risk of loosening and falling off, and ensuring stable connection.
Multiple surface treatment processes, rust-resistant and durable appearance
The stainless steel model is treated with passivation anti-rust treatment, the carbon steel model is treated with galvanizing / blackening anti-rust treatment. The surface has high smoothness, no oxide scale, no scratches, strong appearance texture, and at the same time enhances corrosion resistance, reduces stress concentration, and extends the product's service life; the black model can also be adapted for appearance decoration, personalized modification scenarios.
Full specification coverage, customized service
Covering M3-M16 full series thread specifications, imperial #4-#12, 1/4"-1/2" etc. full size matching, and also supporting non-standard customization. According to customer needs, special materials, special wing ear shapes, fine-threaded butterfly nuts can be customized to meet the personalized tightening requirements of special scenarios.
