S-91847A560 7/8"-9 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Space-saving thin profile allows for use in tight assemblies where standard nuts won't fit, without sacrificing strength.
• Reliable coarse threading (UNC) enables faster assembly and reduced cross-threading risk, boosting installation efficiency.
• Precise Class 2B thread fit ensures smooth engagement with mating bolts, minimizing play and vibration loosening.
• External hex drive design provides excellent torque transmission for secure tightening using common tools.
• Compliance with RoHS 3 and REACH guarantees environmental safety and meets strict regulatory standards for industrial use.
• Durable right-hand thread offers consistent performance in standard applications, ensuring long-term fastener integrity.

Professional Applications & Engineering Value

This 7/8"-9 UNC thin hex nut is engineered from 18-8 stainless steel to address common challenges in industrial settings, such as corrosion from moisture, chemicals, or outdoor exposure. Its thin profile is particularly valuable in confined spaces—like machinery frames, electrical enclosures, or automotive assemblies—where standard nuts would be too bulky. The coarse thread spacing and Class 2B thread fit work together to resist vibration-induced loosening, a critical factor in high-stress applications. By combining a right-hand thread with an external hex drive, this nut ensures compatibility with standard tools and bolts, streamlining maintenance and reducing downtime. Ideal for construction, manufacturing, and marine industries, it delivers reliable performance while meeting RoHS and REACH environmental mandates.

Specification Summary & Compliance

This hex nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent dimensional accuracy. Key specifications include a thread size of 7/8"-9, width of 1 5/16", and height of 31/64". It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for global industrial applications.
