Carbon Steel Round Head Hexagon Socket Bolts

Product  introduction

Carbon steel round head hexagon socket bolts are made of high-strength medium carbon steel and undergo quenching and tempering treatments. They combine excellent tensile strength and good toughness, with a maximum tensile strength of up to 1200MPa. These bolts can withstand high-intensity loads and severe vibrations, ensuring the reliability of fastening connections. The unique round head shape, with its smooth and full arc design, not only effectively avoids scratches and potential safety hazards caused by sharp edges but also enhances the aesthetic appeal, making them suitable for equipment and components with certain appearance requirements.​

The hexagon socket structure can tightly engage with special wrenches, enabling high torque output and easily meeting high tightening force requirements. It can also be flexibly operated in narrow spaces, facilitating installation and disassembly. Our products are available in various strength grades, such as 4.8, 8.8, and 10.9. The thread sizes range from M3 to M30, and the length ranges from 10mm to 200mm, adapting to different material thicknesses and working conditions. The surface is treated with anti-rust processes such as galvanizing and blackening, significantly improving corrosion resistance, and making them suitable for a variety of industrial environments and daily use scenarios.​

Widely used in fields such as mechanical equipment manufacturing, automotive parts assembly, furniture production, and construction decoration, our products are manufactured and tested in strict accordance with GB national standards. We have a professional team that provides one-stop services from product selection to technical consultation, offering customers efficient and stable fastening solutions.
