S-92174A680 1 1/8"-12 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with durable brass construction, ideal for harsh environments and extended service life.
• Optimized weight and material usage from the thin profile design, reducing overall assembly bulk without sacrificing strength.
• Excellent torque transmission and grip via the external hex drive, enabling secure tightening with standard tools.
• Reliable fine thread engagement with the 1 1/8"-12 UNF thread, providing superior vibration resistance in critical applications.
• Precise and consistent fit ensured by Class 2B thread tolerance, promoting smooth assembly and reducing cross-threading risks.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and eligibility for global industrial supply chains.
• Right-hand thread direction for standard, intuitive installation and removal in common machinery and equipment.

Professional Applications & Engineering Value

This 1 1/8"-12 UNF Class 2B thin hex nut is engineered to address common industrial challenges such as corrosion, vibration loosening, and space constraints. The brass material offers inherent resistance to rust and galvanic corrosion, making it a reliable choice for marine, plumbing, and electrical applications where moisture is a concern. Its fine UNF threads and Class 2B fit provide a tighter, more secure connection than coarse threads, significantly reducing the risk of loosening under dynamic loads. The thin profile allows for use in compact assemblies where a standard hex nut would be too bulky, while the external hex drive ensures maximum torque application with common wrenches. This combination of features delivers long-term reliability and performance in industrial fastening systems, from machinery manufacturing to precision equipment maintenance.
