- Superior torque transmission via the external square drive and square head, enabling secure tightening with standard tools and reducing installation time.
- Reliable fastening in demanding environments thanks to the coarse UNC thread and Class 2A fit, which resists vibration and allows for easier alignment.
- Enhanced component longevity with a cup tip design that minimizes surface damage and provides consistent, secure contact points.
- Streamlined procurement and compliance by meeting ASME B18.6.2 specifications, ensuring dimensional accuracy and interchangeability.
- Environmental and safety assurance through RoHS 3 and REACH compliance, making it suitable for regulated industrial applications.
- Versatile right-hand threading for standard assembly processes, offering broad compatibility across various machinery and equipment.
Professional Applications & Engineering Value
This alloy steel set screw is engineered to address common industrial challenges such as component slippage and fastener failure in high-stress assemblies. The 5/8"-11 UNC coarse thread and Class 2A thread fit ensure quick installation and reliable performance in vibrating environments, reducing maintenance downtime. Its square head with external square drive provides excellent torque resistance, making it ideal for heavy-duty applications like machinery shafts, pulleys, and couplings. The Rockwell C45 hardness and robust material composition prevent wear and corrosion, extending service life in demanding sectors such as manufacturing, automotive, and construction. By integrating ASME B18.6.2 standards, it guarantees precision and safety, while RoHS and REACH compliance supports sustainable operations.
Specification Summary & Compliance
This set screw adheres to precise dimensional tolerances, including a Class 2A thread fit for consistent engagement and UNC coarse threading per industry norms. It conforms to ASME B18.6.2 manufacturing specifications for reliability and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets.
