Carbon Steel Flange Nuts

Made of high-quality medium carbon steel and strengthened by quenching and tempering, carbon steel flange nuts feature high strength and toughness, ideal for heavy-duty applications in machinery and construction. The flange design enlarges the contact area, evenly distributing pressure to prevent slipping and rotation, while precision-cut internal threads ensure a tight fit with bolts for secure connections.

Available in strength grades from 4.8 to 10.9 and covering thread sizes from M3 to M36, these nuts meet diverse needs. Their surfaces are treated with anti-rust processes like galvanizing and blackening for enhanced corrosion resistance. Produced in strict compliance with GB national and ISO international standards, our professional team offers selection support, delivering reliable fastening solutions for various projects.
