Carbon Steel Hexagon Nuts

Product  introduction

Carbon steel hexagon nuts are made of high-quality medium carbon steel and processed by quenching and tempering, providing high strength and good toughness. Available in multiple strength grades from 4.8 to 12.9, they meet the requirements of high-intensity applications such as machinery manufacturing, construction projects, and equipment installation. The hexagonal structure is compatible with common wrenches, enabling quick tightening and disassembly. The internally threaded nuts are precisely machined to fit bolts tightly, ensuring a stable connection and effectively preventing loosening.

With thread sizes ranging from M3 to M64, these nuts are suitable for bolts of different sizes. The surface is treated with anti-rust processes such as galvanizing, blackening, and Dacromet, significantly enhancing corrosion resistance, making them suitable for various industrial environments and outdoor working conditions. Manufactured and tested in strict accordance with GB national standards and ISO international standards, our professional team offers selection guidance and after-sales support, providing customers with cost-effective fastening solutions.
