Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw delivers critical vibration resistance for industrial machinery, automotive components, and precision equipment where permanent locking is essential. The nylon patch thread locker technology eliminates the need for additional locking compounds while maintaining secure fastening through extreme temperature cycles from -50°F to 250°F. Engineered with fine thread spacing and Class 3A thread fit, this headless set screw provides maximum engagement strength in tight-tolerance applications. The black-oxide alloy steel construction combined with Rockwell C45 hardness ensures long-term reliability in high-stress environments where corrosion resistance and mechanical strength are paramount. The cup tip design creates positive locking action on shafts and collars, preventing rotational slip in critical motion control systems.
Specification Summary & Compliance
