Product Description

The 1/2-13 Threaded Stud with a 4 Inch Stud Bolt and integrated 1/2-13 Coupling Nut is a heavy-duty fastening solution designed for industrial applications requiring robust mechanical connections. This assembly combines a 4-inch-long stud bolt with 1/2-13 unified threads on both ends and a matching coupling nut, enabling secure linkages in structural frameworks or machinery. Constructed from grade-specific steel with corrosion-resistant coatings, it operates reliably in temperatures ranging from -40°C to 120°C, suitable for environments in construction, automotive assembly, and heavy equipment. The threaded stud ensures precise alignment and load distribution, while the coupling nut simplifies installation without requiring specialized tools. Though optimized for high tensile strength, prolonged exposure to extreme vibration or chemical agents may necessitate periodic inspections. Its standardized 1/2-13 thread pitch guarantees compatibility with industry-standard fixtures, offering durability and interchangeability across industrial systems.
