Professional Applications & Engineering Value
This Grade 5 zinc-plated steel hex nut delivers critical engineering solutions for applications requiring left-hand threading where standard right-hand threads would loosen under rotational forces. The thin profile design provides significant space advantages in compact assemblies while maintaining full Grade 5 strength classification. Engineered with UNF fine threads (7/16"-20) and Class 2B thread fit, this fastener ensures precise engagement in machinery, automotive, and industrial equipment where reverse-thread applications prevent accidental disassembly. The zinc-plated steel construction offers substantial corrosion protection, making it ideal for environments exposed to moisture or chemicals, while the external hex drive facilitates efficient installation in high-volume production settings.
Specification Summary & Compliance
This left-hand thread hex nut features precise Class 2B thread fit tolerances with UNF fine thread specification (7/16"-20). Manufacturing complies with industry standards for Grade 5 strength classification, dimensional accuracy (11/16" width, 1/4" height), and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions.
