Blade nuts, also known as butterfly nuts or ingot nuts, are standard hand tightened components with integrated wing shaped blades on both sides. They do not require tools such as wrenches or sockets, and can be easily disassembled and assembled by hand. They are convenient and efficient to operate, and are widely used in equipment structures that require frequent disassembly and fast assembly. The product includes various materials such as galvanized carbon steel and 304/316 stainless steel, with complete specifications that match various metric thread standards. At the same time, special styles such as enlarged blades, thickened bodies, and non-standard tooth spacing can be customized according to needs. The raw materials are selected from high-quality steel and stamped and forged into one piece. The blade and nut body are seamlessly integrated, and the structure is firm and not easy to break; The internal thread is processed by precision rolling, with a full and regular tooth shape, tightly engaged with the screw, and stable locking. It is not easy to slip or trip after repeated disassembly and assembly. The surface has undergone anti-corrosion treatments such as electroplating, hot-dip galvanizing, polishing, and blackening, resulting in a uniform and smooth coating that effectively prevents rust and oxidation. It is suitable for different usage environments such as indoor and humid outdoor environments. The entire process is tested by thread gauges, tension, salt spray, etc., with standardized dimensions and strong interchangeability. Compared to ordinary hex nuts, the biggest advantage of blade nuts is that they can be quickly tightened without tools, greatly improving the efficiency of disassembly and assembly. They are suitable for scenarios that require frequent debugging, maintenance, and replacement of parts. Widely used in wind turbine equipment, photovoltaic brackets, instrument cases, fixtures, photography equipment, furniture hardware, medical equipment, small mechanical equipment, pipeline buckles, exhibition stands and other fields. Regular standard specifications are readily available in stock, and customized special blade nuts with large blades, thickened blades, and high-temperature and anti-corrosion properties can also be made according to drawings and samples.
