Double end stud bolts, also known as dual-ended threaded rods, are essential fasteners designed with threads on both ends and an unthreaded section in the middle. They are widely used in industrial machinery, piping systems, flange connections, and equipment assembly where precise tension and alignment are critical.
The M series stud bolts refer to metric-sized threads, such as M6, M8, M10, M12, M16, M20, M24, and more, providing standardization and compatibility with a wide range of nuts and tapped holes.
