Production Process
Material Selection: We use SCM435 / 40Cr alloy steel specifically designed for Class 12.9 applications, ensuring high strength, toughness, and resistance to breakage.
Cold Forging: Round steel is forged into bolt heads and shanks using large cold forging machines for one-step forming, resulting in high density and superior tensile strength.
Thread Processing: Threads are rolled using thread rolling machines rather than being turned, creating smoother threads with higher strength and reduced risk of thread slipping.
