Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for precision industrial applications where vibration resistance and permanent positioning are paramount. The Class 3A UNF fine threads maintain tight tolerances in high-stress assemblies, while the 90° cone point creates permanent seating in shafts, collars, and pulleys. The headless design with hex drive provides flush mounting in confined spaces, making it ideal for machinery, automotive components, and precision equipment. Combined with Rockwell C45 hardness, this set screw prevents loosening under dynamic loads, ensuring long-term reliability in demanding industrial applications.
