• Space-saving thin profile design allows for installation in tight or confined spaces without compromising performance.
• Secure left-hand thread engagement prevents loosening in applications with counter-clockwise rotational forces, enhancing safety.
• Precise UNC coarse threading with Class 2B fit ensures easy assembly, reduced cross-threading risk, and consistent fastening.
• Wide compatibility with standard 3/4"-10 UNC bolts and components in inch-based systems, simplifying sourcing and replacement.
• Compliance with RoHS 3 and REACH regulations guarantees environmentally safe materials and meets international industry standards.

Professional Applications & Engineering Value

This Grade 5 zinc-plated steel hex nut is engineered to address critical challenges in industrial settings, such as vibration-induced loosening and space constraints. The left-hand thread design is ideal for machinery or equipment where reverse rotation is common, providing a reliable fastening solution that resists unintentional disassembly. Its thin profile reduces weight and bulk, making it perfect for compact assemblies in automotive, construction, or heavy machinery without sacrificing the high tensile strength of Grade 5 steel. The zinc plating offers a durable barrier against rust and corrosion, ensuring long-term performance in demanding environments. Combined with UNC coarse threads, it allows for quick installation and removal, minimizing downtime in maintenance and repair operations.

Specification Summary & Compliance

This hex nut features a 3/4"-10 UNC coarse thread with Class 2B thread fit for standard tolerance and easy assembly. Manufactured from zinc-plated steel with dimensions of 1 1/8" width and 27/64" height, it adheres to inch system standards. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
