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.
