Professional Applications & Engineering Value

This 4-40 UNC fully threaded rod is engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced failure. The zinc-plated steel material provides a protective barrier against moisture and chemicals, extending service life in machinery, electrical enclosures, and framework assemblies. With coarse thread spacing and right-hand thread direction, it enables rapid adjustments and secure connections in production lines and maintenance operations. The combination of 50,000 psi tensile strength and Rockwell B61 hardness ensures that the rod maintains structural integrity under dynamic loads, making it ideal for applications requiring repeated assembly or exposure to stress. Its full threading allows for flexible positioning of nuts and components, reducing the need for custom-cut fasteners and streamlining inventory management.

Specification Summary & Compliance

This threaded rod adheres to UNC thread standards with a Class 1A thread fit for general-purpose use, ensuring dimensional accuracy and compatibility with standard nuts. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming the absence of restricted substances for safe industrial applications. The product is manufactured to deliver consistent performance with coarse thread spacing and right-hand thread direction, supporting reliable fastening in various engineering contexts.
