Professional Applications & Engineering Value
This 7/8"-9 UNC set screw delivers critical performance in demanding industrial settings where component slippage can cause equipment failure. The steel construction with Rockwell B80 hardness provides excellent resistance to wear and shear forces, while the coarse UNC thread enables rapid installation in soft materials or corroded assemblies. The square head design with external drive allows maximum torque application without stripping, making it ideal for permanent positioning in machinery, conveyor systems, and heavy equipment. Its 3" length and cup tip ensure deep penetration into shafts and collars, preventing rotational movement in high-vibration environments. Engineered to ASME B18.6.2 standards, this set screw maintains dimensional consistency for reliable replacement and maintenance operations.
Specification Summary & Compliance
This set screw features Class 2A thread fit with UNC 7/8"-9 coarse threading, manufactured to precise dimensional tolerances per ASME B18.6.2 specifications. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety in industrial applications. The right-hand thread direction and external square drive provide standardized installation compatibility across equipment platforms.
