Professional Applications & Engineering Value
This Grade 5 steel hex nut delivers critical engineering solutions for heavy-duty industrial applications where fastener failure is not an option. The extra wide hex profile provides superior wrench contact surface, distributing torque evenly to prevent stripping during high-tension assembly. The 2 1/4"-4 1/2 UNC coarse thread with Class 2B fit ensures rapid installation while maintaining vibration resistance in equipment subjected to constant stress. Manufactured from high-strength steel, this industrial fastener maintains structural integrity under extreme loads, making it ideal for construction machinery, mining equipment, and large-scale structural frameworks where reliability and durability are paramount.
Specification Summary & Compliance
This extra wide hex nut features precise Class 2B thread fit per UNC standards with coarse thread spacing for optimal performance. Dimensions include 3 1/2" width across flats and 2 13/64" height with right-hand thread direction. The fastener meets Grade 5 strength requirements and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across global industrial markets.
