S-92683A840 5/16"-18 Hex Nuts

Key Features & Benefits at a Glance

• Superior load distribution with an extra-wide thin profile that reduces surface pressure and prevents material damage in frequent assembly applications.
• Excellent corrosion resistance thanks to the brass material, ensuring long-term reliability in humid or demanding industrial environments.
• Quick and secure installation with coarse UNC threading and Class 2B thread fit, providing smooth engagement and reducing cross-threading risks.
• Enhanced torque application via the external hex drive design, allowing for easy tightening with standard tools and minimizing slippage.
• RoHS 3 compliance with exemption for lead in copper alloy, meeting environmental standards without sacrificing performance in specialized applications.
• Dimensional precision with consistent 9/16" width and 13/64" height, ensuring reliable fit and interchangeability in inch-based assemblies.
• Durable right-hand threading for standard clockwise tightening, offering compatibility with common components and reducing assembly errors.

Professional Applications & Engineering Value

This 5/16"-18 UNC brass hex nut is engineered to address common challenges in industrial fastening, such as corrosion-induced failure and uneven stress distribution. The extra-wide thin profile spreads clamping force more effectively, reducing the risk of loosening under vibration in machinery, automotive, or electrical enclosures. Made from corrosion-resistant brass, it excels in moist or chemical-exposed settings, extending service life without frequent replacements. The Class 2B coarse thread and external hex drive simplify installation in tight spaces, boosting efficiency on production lines. Ideal for plumbing, HVAC, and marine applications, this nut ensures reliable performance where RoHS compliance and material durability are critical.

Specification Summary & Compliance

This hex nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent accuracy and ease of assembly. Dimensions include a 9/16" width and 13/64" height, manufactured to precise inch measurements. It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys, ensuring environmental safety while maintaining mechanical integrity in line with industry norms.
