S-92117A790 3/4"-10 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to high-quality brass construction, ideal for humid or chemically aggressive environments
• Reliable left-hand thread engagement prevents loosening in applications with counter-clockwise rotational forces
• Space-saving thin profile allows for installation in tight or restricted areas where standard nuts won't fit
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force for secure fastening
• Robust UNC coarse threading provides excellent wear resistance and reduces the risk of cross-threading during installation
• Easy external hex drive enables quick installation and removal with standard wrenches, improving maintenance efficiency
• Full regulatory compliance with REACH and RoHS 3 standards, making them suitable for regulated industrial applications

Professional Applications & Engineering Value

This left-hand brass hex nut addresses critical engineering challenges in applications requiring reverse-thread security. The brass material provides inherent corrosion resistance, eliminating rust concerns in marine, plumbing, and electrical applications where galvanic corrosion is a risk. The thin hex nut profile offers significant space advantages in compact assemblies, while the UNC coarse thread maintains superior strength and durability in high-vibration environments. These left-hand thread fasteners are specifically engineered for rotating machinery, mixer blades, and safety-critical applications where standard right-hand threads would naturally loosen. The combination of external hex drive and precise Class 2B thread fit ensures reliable performance in maintenance-intensive industrial settings.

Specification Summary & Compliance

This 3/4"-10 UNC left-hand brass thin hex nut features Class 2B thread fit per ASME B1.1 standards, ensuring proper clearance and assembly compatibility. The coarse thread spacing follows UNC specifications for optimal performance in industrial applications. Manufacturing complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) standards with exemption 6(c) for lead in copper alloys. Dimensional specifications include 1-1/8" width across flats and 27/64" height, maintaining precise inch system measurements for consistent performance.
