SS 316 Stud Bolts - Marine Grade Flange Fasteners

The SS 316 Stud Bolt is an essential threaded fastener used to join two flanges together, typically supplied with two heavy hex nuts (one for each end). Stud bolts are fully threaded rods cut to length, often with a specific chamfered end style. The inclusion of molybdenum in the SS 316 marine grade alloy grants these fasteners superior resistance to pitting and crevice corrosion, making them highly reliable in pipelines handling aggressive chemicals, steam, or exposed to coastal/offshore environments. Zeron Fasteners specializes in manufacturing and supplying high-quality SS 316 Stud Bolts, including those conforming to ASTM A193 Grade B8M, ensuring they provide the necessary preload and long-term joint integrity required for critical process piping and pressure vessel connections.
