FAQ

Q: What materials are available?

A: Carbon steel, alloy steel, stainless steel, brass, aluminum, and customized materials.

Q: What standards do your nuts comply with?

A: DIN, ISO, ASTM, ANSI, UNC, UNF, and project-specific standards.

Q: What production methods do you use for your nut ranges—cold heading or hot forging?

A: We utilize both based on size and mechanical requirements. Standard-size nuts (typically up to M24 or 1") are produced using high-speed multi-station cold heading for optimal material efficiency and dimensional precision. Extremely large-diameter or thick structural nuts are manufactured via precision induction hot forging to guarantee optimal grain structure flow and strength.

Q: Do you support large-scale orders and long-term supply agreements?

A: Yes, we offer customized production, wholesale supply, project procurement support, as well as strategic long-term cooperation on a global scale.

Q: In general, how long can delivery be made after receiving an order?

A: Regular orders can be completed and shipped within 15-20 working days after receiving the deposit and confirming product details.
