A stainless steel hex bar is a solid long product with a hexagonal (six-sided) cross section, manufactured for applications requiring positive spanner grip, resistance to rotation, and precise machining. Compared to round bars, hex bars provide improved torque handling and are commonly used in fasteners, studs, nuts, bolts, and machined components.
Stainless steel hex bars are produced from solid stainless steel billets using hot rolling, cold drawing, or forging processes, followed by heat treatment and finishing operations to meet dimensional and metallurgical requirements.
Inox Steel India is one of the established manufacturers, suppliers, and exporters of stainless steel hex bars in India, supplying to engineering and industrial projects across GCC countries, the Middle East, African nations, Europe, and North & South America.
We supply stainless steel hex bars manufactured from premium austenitic stainless steel grades — 304, 304L, 316, 316L, 321, and 347 — conforming to ASTM A276 / ASTM A479 standards. These hex bars are widely used where torque transmission, corrosion resistance, and dimensional accuracy are critical.
With ISO-compliant manufacturing and strict quality control, stainless steel hex bars supplied by Inox Steel India offer consistent across-flat dimensions, uniform mechanical properties, and reliable machining performance for industrial applications.
These characteristics make stainless steel hex bars suitable for engineering, marine, chemical, food, and fabrication applications.
Stainless steel hex bars are supplied in the following grades:
SS 304 / 304L – General corrosion resistance, fabrication and food-grade use
SS 316 / 316L – Enhanced resistance to chlorides and marine environments
SS 321 – Stabilized grade for elevated temperature service
SS 347 – Improved resistance to intergranular corrosion and creep
All materials are supplied as per ASTM A276 / ASTM A479 specifications.
