Home > Hex Bars
Hex Bars (Hexagonal Bars) are precision-engineered metal bars with a six-sided cross-section, widely used in fasteners, bolts, nuts, valves, fittings, precision machining, aerospace, and marine engineering. Their geometry allows for easy gripping, superior torque transfer, and dimensional stability.
Hex Bars are produced in stainless steel, carbon steel, alloy steel, tool steel, duplex, nickel alloys, copper alloys, and titanium—each selected based on strength, corrosion resistance, machinability, and end-use application.
Compared to round and square bars, hex bars offer:
Hex bars are crucial for industries requiring high-strength fasteners, threaded components, hydraulic fittings, high-pressure valves, and precision-engineered parts.
Hex Bars are produced through multiple metallurgical processes depending on the end-use:
With over a decade of experience and multi-material capability — from Stainless Steel to Carbon, Alloy, Duplex, and Nickel Alloys with Product Pipes, Tubes, Bars we serve the world’s most demanding industries with trust, traceability, and timely delivery.
