The wing nut is a fastener with double wing handles, with core materials being zinc alloy (e.g., Zamak 3, Zamak 5). Its double-wing structure enables quick manual tightening/loosening without the need for wrenches or other tools. The central threaded hole is compatible with connecting parts such as bolts and screws, and it is widely used in scenarios requiring frequent disassembly or quick fixation, balancing practicality, aesthetics, and moderate corrosion resistance.

• Precise Casting Performance: Adopts high-pressure die casting process, ensuring dimensional accuracy (tolerance ≤ ±0.05mm) and smooth surface without burrs, suitable for scenarios with aesthetic requirements.
• Moderate Mechanical Properties: The transition between wings and threaded holes is optimized with rounded corners, reducing stress concentration; zinc alloy’s toughness avoids brittle fracture, better than plastic in impact resistance.
• Anti-slip and Aesthetic Integration: Wing surfaces are designed with fine grid patterns or matte texture, enhancing grip friction while maintaining a neat appearance, suitable for visible assembly parts.

• Furniture and Decoration: Wooden furniture connectors, glass bracket fixings, cabinet door hinges. Zinc alloy’s smooth surface and diverse plating colors (chrome, bronze) match home aesthetics.
• Electronics and Instruments: Shell fixing of small appliances (blenders, coffee machines), panel installation of test instruments. Moderate load-bearing meets lightweight equipment needs.
• Medical Auxiliary Devices: Bedside rail adjusters, wheelchair accessory fixings. Chromium-plated surface is easy to clean, meeting basic hygiene requirements.
• Light Industrial Assembly: Toy parts, display rack fasteners, exhibition equipment. Die-casting process ensures batch consistency, suitable for mass production.

• Installation Points: Align with bolt threads and tighten manually; avoid excessive torque (recommended ≤ 15N·m for M8) to prevent wing deformation. It is advisable to use with a plastic washer to protect the contact surface.
• Maintenance Recommendations:
  • Avoid long-term exposure to strong acids/alkalis (e.g., cleaning agents with high chlorine content) to prevent surface plating damage.
  • For outdoor temporary use (e.g., garden tools), wipe with a dry cloth monthly to remove moisture.
  • If surface rust spots appear, gently polish with a soft cloth and apply a thin layer of anti-rust oil to extend service life.

• Aesthetic Adaptability: Diverse surface treatments (chrome plating, electrophoresis) and fine casting texture make it suitable for visible assembly parts, superior to carbon steel in appearance.
• Cost-Effectiveness: Lower than stainless steel (about 60% of 304 stainless steel cost) while offering better corrosion resistance than iron, balancing performance and budget.
• Processing Flexibility: Die casting allows complex wing shapes (e.g., curved wings, logo embossing), meeting customized design needs.

With its combination of operability, aesthetics, and moderate performance, zinc alloy wing nuts are an ideal choice for light-load, appearance-oriented, and medium-corrosion-resistance scenarios.
