ASTM A193 B7 Stud Bolts with A194 2H Nuts

Engineered for critical high-temperature and high-pressure applications, these ASTM A193 B7 stud bolts are paired with A194 2H nuts to ensure superior strength and reliability in demanding industrial environments. Manufactured from high-strength alloy steel, this fastening system is ideal for flanged connections in refineries, power plants, and chemical processing facilities where thermal stability and resistance to stress relaxation are paramount.

Our production process in Al Jubail ensures precise cutting and threading to exact specifications, minimizing material waste and ensuring consistent thread quality. To extend service life and prevent galling or corrosion, we offer multiple surface treatments: plain finish for standard applications, hot-dip galvanizing for enhanced corrosion resistance, or PTFE coating for low-friction assembly and superior chemical resistance. Each shipment is accompanied by EN 10204 Type 3.1 material test certificates, providing full traceability from mill to site.
