Professional Applications & Engineering Value

This Grade 5 steel hex nut delivers critical engineering solutions for industrial applications where vibration resistance and structural integrity are paramount. The extra wide profile (3 7/8") distributes clamping force more effectively across larger surface areas, preventing joint loosening in heavy machinery, construction equipment, and structural steel frameworks. The 2 1/2"-4 UNC coarse threading provides rapid assembly advantages while the Class 2B thread fit ensures consistent engagement without binding. Manufactured from high-strength steel with external hex drive compatibility, this fastener maintains reliability in high-torque applications and withstands dynamic loading conditions that would compromise standard fasteners.

Specification Summary & Compliance

This heavy-duty hex nut features precision 2 1/2"-4 UNC coarse threading with Class 2B thread fit per ASME/ANSI standards, ensuring consistent engagement and dimensional accuracy. The fastener meets Grade 5 strength requirements with dimensions of 3 7/8" width and 2 29/64" height. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and chemical substance restrictions for industrial use across global markets.
