Machine screw hex nuts are precision-engineered fasteners designed to be paired with machine screws in a wide range of applications. They offer reliability and ease of use. Characterized by their six-sided shape, these nuts allow for easy tightening with standard tools. They are commonly made from materials like stainless steel and brass, but for demanding environments, exotic alloys such as Inconel, Hastelloy, and titanium are employed. These high-performance materials provide superior strength, corrosion resistance, and thermal stability, making them ideal for aerospace, marine, and chemical processing industries where conventional metals would fail under extreme conditions. Hex nuts remain essential components in mechanical assemblies.
Nickel Systems stocks a wide range of machine screw hex nuts in various exotic alloys. Check out our specification and technical data information below to select the right fastener for your next project.
