Professional Applications & Engineering Value
This Grade 8 thin hex nut delivers exceptional engineering value in heavy machinery, structural steel connections, and industrial equipment where maximum tensile strength and corrosion resistance are critical. The zinc yellow-chromate-plated steel construction provides a durable barrier against oxidation and chemical exposure, significantly extending service life in challenging environments. The thin hex nut profile offers substantial space savings while maintaining full Grade 8 strength, making it ideal for applications with limited clearance. Precision-machined to ASME B18.2.2 standards with UNC coarse threading, this fastener ensures reliable performance in vibration-prone applications across construction, manufacturing, and transportation sectors.
Specification Summary & Compliance
Manufactured to exact ASME B18.2.2 specifications with Class 2B thread fit tolerance for consistent threading performance. Features 7/8"-9 UNC coarse thread with right-hand direction and external hex drive. Dimensions include 1 5/16" width and 31/64" height. The zinc yellow-chromate plating on steel substrate provides enhanced corrosion protection while maintaining Grade 8 strength classification for heavy-duty applications. Complies with industry standards for dimensional accuracy and mechanical properties.
