- Full regulatory compliance with RoHS 3 and REACH standards for global industrial supply chain integration
Professional Applications & Engineering Value
Engineered for industrial fastening systems, this thin hex nut addresses critical space constraints while maintaining structural integrity. The zinc-plated steel construction creates a sacrificial barrier against oxidation, significantly extending service life in manufacturing equipment, structural assemblies, and machinery maintenance. The coarse UNC thread profile ensures rapid installation in high-vibration environments where fine threads might loosen, while the Class 2B thread fit provides optimal clearance for smooth engagement without compromising joint security. This combination makes the fastener particularly valuable in assembly line applications, heavy equipment maintenance, and construction projects where corrosion resistance and installation efficiency are paramount.
Specification Summary & Compliance
This inch-system hex nut features precise Class 2B thread fit tolerances per UNC standards with dimensions of 2 1/4" width and 27/32" height. Manufactured to Grade 2 strength specifications with right-hand coarse threading (1 1/2"-6 UNC). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial applications.
