Key Features & Benefits at a Glance
- Exceptional holding power from the coarse UNC thread design, ensuring secure fastening in high-vibration environments
- Superior durability with Rockwell B80 hardness steel construction, resisting wear and deformation under heavy loads
- Easy installation and removal via the external square drive and square head, allowing high torque application with standard tools
- Reliable thread engagement thanks to Class 2A thread fit, providing consistent performance and reducing cross-threading risks
- Enhanced grip and positioning from the cup tip design, minimizing component slippage in assemblies
- Long-term corrosion resistance and environmental compliance, meeting RoHS 3 and REACH standards for industrial safety
- Interchangeable and standardized per ASME B18.6.2, ensuring compatibility with existing equipment and global engineering specs
Professional Applications & Engineering Value
This 7/16"-14 UNC steel set screw is engineered to address critical challenges in heavy machinery, automotive, and construction sectors where vibration loosening and component misalignment are common. The coarse thread and Class 2A fit provide rapid assembly and reliable clamping force, while the square head with external drive enables high-torque tightening without stripping. Made from hardened steel (Rockwell B80), it withstands repetitive stress and harsh conditions, and the cup tip bites into shafts or hubs to prevent rotational slip. Ideal for securing gears, pulleys, and collars, this 3-inch set screw delivers consistent performance in demanding industrial fastening applications, reducing maintenance downtime and enhancing operational safety.
Specification Summary & Compliance
This set screw adheres to ASME B18.6.2 manufacturing standards, with precise Class 2A thread fit for consistent dimensional accuracy. The UNC coarse thread (7/16"-14) and right-hand direction ensure broad compatibility. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmentally safe and restricted-substance-free use in global markets.
