Professional Applications & Engineering Value
This 5/8"-11 UNC square head set screw delivers exceptional engineering value in demanding industrial environments where secure fastening is critical. The steel construction with Rockwell B80 hardness provides the necessary strength to withstand vibration and heavy loads in machinery assembly, power transmission systems, and manufacturing equipment. The external square drive design allows for maximum torque application without stripping, while the cup tip creates a permanent seating point that prevents component slippage. The coarse thread configuration ensures rapid installation and removal, making it ideal for maintenance applications where downtime reduction is essential. Engineered to ASME B18.6.2 standards, this heavy-duty fastener maintains dimensional consistency across production runs for reliable performance in OEM and MRO applications.
Specification Summary & Compliance
This square head set screw features precise Class 2A thread fit with 5/8"-11 UNC coarse threading and right-hand thread direction, manufactured to exacting dimensional tolerances. The fastener complies with ASME B18.6.2 specifications for square head set screws, ensuring mechanical properties and dimensional accuracy. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for industrial safety and environmental protection.
