Professional Applications & Engineering Value
This 3/4"-10 UNC Class 2A steel square head set screw delivers critical engineering solutions for industrial applications where vibration resistance and maximum clamping force are paramount. The coarse thread configuration provides superior holding power in soft materials and high-vibration environments, while the square head design enables high-torque installation without stripping. The Rockwell B80 hardness ensures the screw maintains its structural integrity under repeated loading cycles, making it ideal for heavy machinery, manufacturing equipment, and automotive assemblies. The cup tip creates concentrated pressure points that prevent shaft slippage in pulley systems, gear assemblies, and coupling applications, ensuring long-term operational reliability in demanding industrial settings.
Specification Summary & Compliance
This set screw features 3/4"-10 UNC coarse threads with Class 2A thread fit for precise dimensional tolerance. Manufactured to ASME B18.6.2 specifications with a 2" length, 3/4" head width, and 37/64" head height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international quality standards for industrial fasteners.
