High-Strength Fasteners for Flange
and Pressure Joint Assemblies
Stud bolts are externally threaded, headless fasteners used in conjunction with two nuts to secure flange joints and other pressure system connections. They offer a robust and reliable alternative to traditional bolt-and-nut assemblies, especially in high-temperature, high-pressure environments.
These fasteners are commonly used in the oil & gas, petrochemical, power, and processing industries, where critical joint integrity is essential.
