Professional Applications & Engineering Value
These Grade 5 zinc-plated steel thin hex nuts deliver critical engineering advantages for industrial fastening systems requiring both strength and corrosion protection. The UNC coarse thread configuration ensures rapid assembly in high-vibration environments where fine threads might loosen, while the thin profile maintains structural integrity in space-constrained assemblies. The zinc plating provides sacrificial protection against rust and corrosion, extending service life in manufacturing plants, construction equipment, and transportation infrastructure. With 2"-4 1/2 thread sizes covering common industrial requirements, these nuts offer reliable performance in heavy machinery, structural steel connections, and maintenance applications where Class 2B thread fit guarantees consistent clamping force without binding.
Specification Summary & Compliance
Manufactured to ASME B18.2.2 standards with Class 2B thread fit tolerance for precise engagement. Features UNC coarse threads in right-hand direction with sizes ranging from 2" to 4 1/2. Constructed from zinc-plated steel with dimensional specifications of 3" width and 1 3/32" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substance management.
