Frequently Asked Questions

Q: What are the primary benefits of using a flange nut over a standard nut?

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.

Q: Which materials are best for outdoor corrosive environments?

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.

Q: Do you support custom sizes beyond the M8-M30 range?

While our standard range is M8-M30, we are a direct factory and can manufacture custom sizes and specifications based on your technical drawings.

Q: What is the difference between Grade 8.8 and Grade 10.9 flange nuts?

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.

Q: Can I get free samples to test the quality before placing a bulk order?

Yes, we provide free samples for quality verification to ensure our products meet your exact specifications and performance requirements.

Q: What are your standard packaging options for international shipping?

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.
