Stud Bolt
Stud Bolts
Our high-performance Stud Bolts are fully threaded rods designed for flange connections in pipelines, valves, and heavy machinery. Unlike standard bolts, they feature threads along their entire length, allowing for tension from both ends using heavy hex nuts. Essential for oil & gas and petrochemical industries, they ensure leak-proof seals under high pressure and temperature conditions.
