Square head bolt , Iran

Square head bolts are mechanical fasteners with a square head, used for high-strength connections in structures, machinery, and industrial equipment. Typically made from carbon steel, alloy steel, or stainless steel with surface hardness of 250–400 HB and tensile strength of 600–1000 MPa. Bolt diameters range from M6 to M36, with lengths from 20 to 300 mm. Threads are manufactured according to ISO or DIN standards, providing high tensile and torque load capacity. Galvanized, chrome, or epoxy coatings enhance corrosion and wear resistance in industrial and construction environments.

Square head bolts are used with nuts and flat or spring washers to ensure secure and uniform connections. Suitable for heavy machinery, steel structures, production lines, and industrial projects. Precise mechanical design reduces loosening, increases connection durability, and extends service life. Quick installation and replacement facilitate easy maintenance.You can order and buy Square head bolt from Iran by contacting us through whatsaap and email.
