Fully threaded stud bolts are manufactured to ASME standards from ASTM A193 Grade B7 alloy steel. Each bolt undergoes hot-dipped galvanization for superior corrosion resistance and extended service life in harsh environments. Standard lengths range from 90 mm to 150 mm, with customized sizes available to meet specific project requirements. These high-strength fasteners are engineered for critical applications in pressure vessels, pipelines, structural steel connections, and heavy machinery assembly.
