Shanghai Metal Corporation is a professional manufacturer and supplier of Square Head Bolt with high quality and reasonable price.
Square Head Bolt is a type of bolt with a square head, which performs well in situations requiring strong fastening and anti rotation due to its unique square design and high torque capability. The square head has a large contact area with the wrench, making it easy to install and disassemble, while effectively preventing the bolt from rotating during the tightening process. The materials of square head bolts are diverse, including carbon steel (such as Q235, 45 # steel), alloy steel (such as 40Cr), stainless steel (such as 304, 316), etc. Surface treatment methods such as galvanizing, blackening, Dacromet, etc. can significantly improve their corrosion resistance and service life. Widely used in fields such as building steel structures, mechanical equipment, automotive chassis, petrochemical pipelines, shipbuilding, and power equipment, square head bolts have become an important choice in general fasteners due to their economic practicality, easy installation, and high reliability. Standard sizes (such as M6, M8, M10, etc.) comply with GB/T specifications and meet different load and environmental requirements, making them an ideal solution for industrial connections and fixation.
