Industrial Fastener Solutions
Fasteners for Heavy Engineering Industry
ASTM A193 B7 stud bolts and high-pressure fasteners for plant and machinery.
Heavy engineering — pressure vessels, heat exchangers, boilers, compressors, and industrial machinery — operates under extreme conditions of pressure, temperature, and mechanical stress. The fasteners in these applications are not interchangeable commodity items; they are engineered components specified to ASTM, ASME, DIN, and IS standards. PGS Fasteners is a specialist supplier for India's heavy engineering sector, providing ASTM A193/A194 series stud bolts, heavy hex nuts, and flange hardware with full material traceability.
