Professional Applications & Engineering Value
This alloy steel set screw delivers exceptional engineering value in demanding industrial environments where vibration resistance and secure positioning are critical. The cup point design creates permanent indentation in mating surfaces, preventing loosening in high-vibration applications such as machinery, automotive assemblies, and power transmission systems. The Rockwell C45 hardness ensures the screw maintains its structural integrity under repeated stress cycles, while the coarse UNC threads provide faster installation and superior performance in softer materials or where debris accumulation is a concern. The external square drive configuration allows for high-torque application without stripping, making it ideal for maintenance-heavy environments where frequent adjustments may be required.
Specification Summary & Compliance
This set screw features precise Class 2A thread fit tolerance for consistent performance and easy assembly. Manufactured to ASME B18.6.2 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The right-hand UNC coarse thread with 1/4"-20 specification provides reliable fastening performance in accordance with industry standards.
