Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for permanent positioning and shaft securing applications. The Class 3A UNF fine threads provide maximum engagement in precision components, while the Rockwell C45 hardness ensures deformation resistance under heavy rotational forces. The hex drive design allows high-torque installation in confined spaces, making it ideal for machinery, automotive assemblies, and industrial equipment where vibration resistance and corrosion protection are paramount. The headless configuration prevents interference in rotating assemblies, offering reliable performance in alignment-critical applications.
