What is ASTM A194 Carbon Steel Stud Bolt?

The ASTM A194 Carbon Steel Stud Bolt is a fastener designed for use in pressure vessels, valves, flanges, and fittings where extreme conditions such as high pressure and temperature are prevalent. Stud bolts are long threaded rods with two heavy hex nuts, used to create secure and sturdy connections in critical industrial systems. They are commonly employed in the oil, gas, chemical, and petrochemical industries, as well as power generation and construction sectors.

ASTM A194 is the standard specification for carbon steel fasteners, specifically for heavy hex nuts used with stud bolts in pressure environments. These fasteners are engineered to deliver exceptional mechanical performance under demanding conditions, offering reliability and long-lasting durability.
