S-92683A885 1 1/2"-6 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass construction, ideal for harsh environments and moisture-prone applications
• Enhanced load distribution with the extra-wide thin profile design, reducing surface pressure and preventing material damage
• Quick and reliable installation thanks to coarse UNC threading and Class 2B fit, minimizing cross-threading risks
• Secure external hex drive ensures firm tool grip and high torque application without slippage
• RoHS 3 compliance with exemption for lead in copper alloys, meeting strict environmental and safety standards
• Durable right-hand threading provides consistent performance in standard industrial assembly operations
• Optimized dimensions (2 3/8" width, 27/32" height) for space-constrained applications requiring robust fastening

Professional Applications & Engineering Value

This 1 1/2"-6 UNC brass hex nut delivers exceptional engineering value in demanding industrial settings where corrosion resistance and reliable fastening are critical. The extra-wide thin profile distributes clamping force evenly, preventing joint loosening under vibration and thermal cycling—common challenges in machinery, plumbing, and electrical enclosures. Made from durable brass material, it naturally resists galvanic corrosion when paired with compatible metals, extending service life in marine, chemical, and outdoor installations. The coarse thread spacing and Class 2B thread fit enable rapid assembly with standard tools, reducing labor time while maintaining secure connections in heavy-duty equipment, piping systems, and structural frameworks.

Specification Summary & Compliance

This hex nut features precise Class 2B thread fit per UNC standards, ensuring consistent engagement and interchangeability. Dimensions include a 2 3/8" width across flats and 27/32" height, manufactured to inch system tolerances. It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys, adhering to environmental directives while maintaining mechanical performance. The nut is designed for use with right-hand coarse threads (1 1/2"-6 UNC) and is suitable for applications requiring ASME-recognized thread forms.
