S-94830A120 7/8"-9 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through flex-top locking design that maintains clamp load under dynamic loads
• Enhanced corrosion protection with cadmium-plated steel construction for extended service life in harsh environments
• Space-saving thin profile (31/64" height) ideal for applications with limited clearance while maintaining full locking performance
• Reliable coarse threading (UNC 7/8"-9) provides quick installation and secure fastening in industrial equipment
• Precise Class 2B thread fit ensures consistent engagement and reduces cross-threading risks during assembly
• External hex drive compatibility allows for standard wrench access and high torque application capability
• Right-hand threading standardization enables straightforward installation and replacement in existing systems

Professional Applications & Engineering Value

This 7/8"-9 UNC thin locknut delivers critical vibration resistance where conventional nuts fail. The flex-top locking mechanism creates consistent friction against mating threads, preventing rotational loosening in machinery subjected to constant vibration and thermal cycling. Manufactured from cadmium-plated steel, these locknuts provide exceptional corrosion resistance in industrial environments exposed to moisture, chemicals, and temperature variations. The thin hex profile solves space-constrained assembly challenges while maintaining full locking functionality. These features make these industrial locknuts ideal for heavy equipment, agricultural machinery, transportation systems, and manufacturing applications where vibration-resistant fastening is critical to operational safety and reduced maintenance intervals.

Specification Summary & Compliance

This locknut features Class 2B thread fit per UNC standards with precise 7/8"-9 coarse threading. The external hex drive measures 1 1/4" across flats with a thin profile height of 31/64". Manufactured to industry standards for dimensional accuracy and performance, these locknuts comply with relevant industrial specifications for locking fasteners and meet RoHS and REACH environmental compliance requirements.
