B7 Studs – High Strength Bolts for Petrochemical

At Liberty Bolt and Nut, we supply ASTM A193 Grade B7 Stud Bolts engineered for superior performance in petrochemical and oil and gas. Manufactured from high tensile alloy steel, our B7 studs are heat-treated to deliver exceptional strength, durability, and resistance to high-pressure and high-temperature environments.

Ideal for pressure vessels, heat exchangers, flanges, and piping systems, these stud bolts are paired with ASTM A194 2H heavy hex nuts to ensure a secure and reliable joint. All products are tested, traceable, and compliant with international standards such as ASTM, ASME, and ISO.

Available in a range of sizes, coatings, and finishes—including zinc-plated, hot-dip galvanized, and PTFE-coated options—our B7 studs are the trusted choice for engineers, fabricators, and maintenance teams across petrochemical plants, refineries, and structural steel projects.

Whether you need custom lengths, full thread or double-ended configurations, or bulk supply, Liberty Bolt and Nut delivers precision fasteners built to last in harsh, corrosive, and high-temperature environments.
