Professional Applications & Engineering Value
This 5/8"-11 UNC steel set screw delivers exceptional engineering value for industrial applications requiring high-strength fastening solutions. The combination of coarse threading and square head drive enables rapid installation in machinery, equipment manufacturing, and assembly operations where vibration resistance is critical. The cup point tip creates permanent indentation in shaft components, preventing rotational slippage in power transmission systems and pulley assemblies. Manufactured from steel with Rockwell B80 hardness, this fastener maintains integrity under heavy loads and repeated stress cycles, making it ideal for construction equipment, agricultural machinery, and industrial automation systems where reliability cannot be compromised.
Specification Summary & Compliance
This set screw features precise Class 2A thread fit with 5/8"-11 UNC coarse thread specification and right-hand threading direction. The fastener complies with ASME B18.6.2 manufacturing standards ensuring dimensional accuracy and performance reliability. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the product meets current environmental safety requirements for industrial use across global markets.
