Nickel Alloy Hex Bar
When machining high-performance fasteners, valves, and fluid fittings, starting with the right shape is critical to your bottom line. 28Nickel supplies premium nickel alloy hex bars that provide a near-net shape for hexagonal components, drastically reducing your CNC milling time and minimizing expensive material waste. Engineered for precision and extreme durability, our hex stock is the foundation of reliable aerospace, marine, and chemical hardware.
Available Alloy Grades for Hex Bar
Fasteners and fittings are often the most stressed points in a corrosive system. We stock hex bars in a comprehensive range of superalloys specifically formulated to resist galling, stress-corrosion cracking, and high-temperature relaxation.

Engineering Advantages of Hex Bar Stock
Choosing hex bar over standard round bar for specific components offers immediate manufacturing efficiencies and structural benefits.
Near-Net Shape Efficiency
For components like heavy hex nuts, bolts, and threaded fluid fittings, the hex bar already provides the finished outer profile. This eliminates the need for extensive CNC milling to create flat wrenching surfaces, drastically reducing cycle times.
Reduced Material Waste
Nickel superalloys are high-value materials. By starting with a hex profile rather than machining down a larger round bar, you significantly decrease scrap generation (swarf) and improve your overall material yield.
Cold Drawn Precision
Our hex bars are primarily supplied in the cold-drawn condition, ensuring exceptionally tight tolerances Across Flats (AF), sharp corners, and a smooth surface finish ready for automated Swiss-style CNC lathes.
Increased Yield Strength
The cold drawing process used to manufacture precision hex bars work-hardens the material, naturally increasing its yield and tensile strength compared to standard hot-rolled conditions.
