Frequently Asked Questions

Q: What is the difference between A2 and A4 stainless steel threaded rods?

A2 stainless steel is ideal for general corrosion resistance in most environments, while A4 stainless steel contains molybdenum, making it superior for marine environments or highly acidic conditions.

Q: Can you produce threaded rods based on non-standard length requirements?

Yes, as a direct factory, we can customize the length of our threaded rods to meet your specific project needs, provided the MOQ of 1,000 pieces is met.

Q: Which surface treatment is best for outdoor industrial use?

For outdoor use, we recommend Zinc Plating or YZP for moderate protection, or A4 stainless steel for maximum resistance against weather and oxidation.

Q: Do your threaded rods comply with ASTM standards?

Absolutely. We manufacture according to ASTM, ANSI, ISO, and DIN standards to ensure global compatibility and safety compliance.

Q: How do I request free samples for DIN 975/976 rods?

You can request free samples by contacting us via email at info@topfastener.com with your specific size and material requirements.

Q: What materials are available for high-strength industrial fastening?

For high-strength applications, we offer 40Cr, B7, and 20MnTiB, which provide superior tensile strength compared to standard carbon steels.
