ASME B18.31.2:2014 Fully Threaded Inch Series Stud

ASME B18.31.2:2014 Fully Threaded Inch Series Stud is intended for flange bolting and demanding fastening applications within inch-based systems. Its full-thread configuration allows nuts to be installed on both ends to generate secure clamping force for piping, valve, and pressure-equipment joints.

This stud is suitable for petrochemical, energy, machinery, and engineering installation projects, especially where flange compression, gasket retention, and repeat maintenance are required. The standardized inch series supports compatibility with matching flanges, nuts, and washer systems.

Material grades and coating options can be selected according to media exposure, temperature conditions, and corrosion requirements, helping improve reliability during long-term operation.
