| Feature Comparison | Standard Nuts + Washers | Our Flange Nuts |
|---|---|---|
| Assembly Speed | Slow (Two components) | Fast (Single component) |
| Load Distribution | Moderate/Uneven | Superior/Uniform |
| Vibration Resistance | Standard | Enhanced Stability |
| Storage Cost | Higher (Dual SKU) | Lower (Single SKU) |
| Long-term Reliability | Prone to loosening | High-locking integrity |
Flange nuts feature an integrated washer-like base that distributes the clamping load over a larger area, reducing material damage and eliminating the need for separate washers, which speeds up assembly.
For highly corrosive environments, we recommend A2 or A4 stainless steel. For industrial outdoor use, our BZP or YZP zinc-plated carbon steel options provide excellent protection.
While our standard range is M8-M30, we are a direct factory and can manufacture custom sizes and specifications based on your technical drawings.
Grade 10.9 offers higher tensile strength and hardness compared to Grade 8.8, making it suitable for critical high-stress applications in metal structural manufacturing.
Yes, we provide free samples for quality verification to ensure our products meet your exact specifications and performance requirements.
We offer standard export packaging in cartons (ctn) or pallets (plt) to ensure the products remain secure during transit. Custom packaging is also available upon request.
