Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in high-vibration industrial applications where reliable locking is critical. The combination of UNC coarse threads and Class 3A precision ensures quick installation and secure fastening in machinery, automotive components, and power transmission systems. The serrated locking mechanism provides permanent resistance to rotational forces, while the cup tip design creates optimal surface contact on shafts and rotating elements. Engineered for heavy-duty applications, this hex drive set screw maintains its integrity under continuous stress, making it ideal for permanent assemblies where disassembly isn't anticipated. The Rockwell C45 hardness ensures the fastener withstands both installation torque and operational loads without deformation.
Specification Summary & Compliance
This 5/8"-11 UNC set screw features Class 3A thread fit for precision applications, manufactured to ASME B18.3 standards. The right-hand coarse threads provide optimal engagement in various materials, while the 1" length offers versatile application coverage. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The black-oxide surface treatment on alloy steel provides corrosion resistance while maintaining dimensional stability.
