Product Description
Grade 8.8 Wing Nut Fastener Galvanized Steel Wing Nut For Fastening Needs
Wing Nuts Are Suitable For Fastening Needs In Multiple Industrial And Household Scenarios
Basic Overview
The wing nut is a fastener with double wing handles, with core materials being carbon steel (e.g., Q235) or iron (mild steel). 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 and economy.
Core Parameters
Parameter Category Specific Parameter Detailed Description
Material and Surface Treatment Main Material Carbon steel (Q235): Tensile strength ≥ 300MPa, high mechanical strength, suitable for medium load-bearing scenarios
Iron (mild steel): Lower cost, good ductility, suitable for light-load fixing
Surface Treatment Hot-dip galvanizing: Zinc layer thickness 20-50μm, salt spray test ≥ 200 hours, excellent rust resistance
Black oxide treatment: Forms a black oxide film, improves wear resistance, suitable for dry indoor scenarios
Specification Parameters Thread Standard Metric (M3-M24), American (1/4"-1"), thread precision 6g, compatible with bolts of the same grade
Wing Span Size M6 model: approx. 25-30mm; M10 model: approx. 35-40mm, ensuring labor-saving grip
Load-Bearing Range M8 carbon steel model: maximum static load ≤ 3kN (when matched with bolt strength)
Design Features
  • Convenient Manual Operation: The double-wing handles eliminate the need for tools, allowing quick manual tightening/loosening, with disassembly and assembly efficiency over 50% higher than ordinary nuts.
  • Structural Reinforcement: Carbon steel/iron materials are formed by forging or stamping; the transition between the wing part and the threaded hole is designed with arcs to reduce stress concentration, and the fracture resistance is better than that of plastic models.
  • Anti-slip Optimization: The wing surface is equipped with horizontal stripes or grid textures to enhance grip friction, preventing slipping in humid environments.
Application Scenarios
  • Industrial and Construction: Agricultural machinery parts, temporary fixation of scaffolding, assembly of storage shelves. Carbon steel models are impact-resistant and suitable for short-term outdoor use.
  • Furniture and Household: Connecting parts for tables and chairs, fixation of wardrobe brackets, base fixation of lighting fixtures. Iron models have low cost and are suitable for civil scenarios.
  • Maintenance and Temporary Fixation: Temporary fixation in automobile/motorcycle maintenance, quick adjustment during equipment debugging, operable without professional tools.
  • General Equipment: Small mechanical protective covers, toolbox latches. Black oxide-treated models are suitable for dry indoor environments.
Installation and Maintenance
Installation Points: Align with the bolt threads and tighten manually. It is recommended to use with a flat washer (to increase the stress area) to avoid wing deformation due to excessive force.
Maintenance Recommendations:
  • For galvanized models, regularly check the integrity of the zinc layer. If local rust is found, promptly polish with sandpaper and touch up with anti-rust paint.
  • Avoid long-term immersion or high-humidity environments (e.g., bathrooms). In such scenarios, additional application of Vaseline for rust prevention is recommended.
  • For iron models used outdoors, maintenance is recommended every 6 months to extend service life.
Advantage Summary
  • Cost Advantage: Carbon steel/iron materials have low raw material costs, with prices only 1/3-1/2 of stainless steel models, suitable for mass use.
  • Strength Adaptability: Meets the needs of most light and medium-load scenarios, with tensile strength superior to plastic models, suitable for both industrial and civil scenarios.
  • Flexible Operation: The double-wing design eliminates the need for tools, allowing non-professionals to operate quickly, improving assembly and maintenance efficiency.
Through reasonable surface anti-rust treatment, carbon steel/iron wing nuts can be stably used in dry, indoor, or short-term outdoor scenarios, making them a cost-effective general fastener choice.
