We produce various fasteners according to GB,ISO, DIN, ANSI, BS, and JIS. Our heavy hex bolts are manufactured from high-grade materials such as stainless steel, carbon steel, and alloy steel. Each bolt is made to precise specifications to ensure consistent and reliable performance. Our bolts are designed to provide a secure and reliable fastening solution for heavy-duty construction and machinery projects.
These bolts have a coarse thread pitch and are available in a range of sizes to suit your requirements. They are typically used in applications where high-strength fastening is required, such as in the construction of bridges, buildings, and heavy machinery.
