Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw is engineered to address common industrial challenges like component slippage and vibration-induced loosening. The cup point design creates a permanent indentation on shafts or hubs, providing unmatched grip that withstands rotational forces in machinery, motors, and precision equipment. Its Class 3A thread fit and coarse UNC threads ensure rapid assembly with minimal cross-threading risks, while the hex drive offers high torque capability for secure fastening in confined spaces. Ideal for heavy-duty applications including automotive assemblies, conveyor systems, and manufacturing tools, this screw delivers reliable performance where failure is not an option.
Specification Summary & Compliance
This set screw features a 3/8"-16 UNC coarse thread with Class 3A fit for precision engagement, manufactured to ASME B18.3 specifications. It maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. The Rockwell C45 hardness and black-oxide surface treatment provide consistent performance in industrial settings.
