SS 304 Stud Bolts

The SS 304 Stud Bolt is a fundamental piece of hardware, consisting of a metal rod that is threaded on both ends or along its entire length. Unlike conventional bolts, it requires two nuts for secure fastening, typically used in flange connections to seal pipelines and equipment, or as foundation anchors. The SS 304 grade (equivalent to ASTM A193 Grade B8) offers excellent corrosion resistance to water, atmospheric conditions, and mild chemicals, making it a reliable, long-lasting choice for pipeline, pump, and valve assemblies. Zeron Fasteners specializes in manufacturing high-quality SS 304 stud bolts, ensuring precise threading and compliance with critical dimensional standards like ASME B16.5 and B18.2.1 for secure joint integrity.
