• Integrated flange design eliminates need for separate washers, providing larger bearing surface and preventing pull-through
• High-temperature performance with nylon insert rated to 250°F (121°C) for demanding industrial applications
• Reliable thread engagement with UNC coarse threads and Class 2B fit ensuring consistent installation and removal
• Grade F strength classification delivers dependable mechanical performance for critical fastening applications
• External hex drive allows for standard wrenching and torque application with common tools

Professional Applications & Engineering Value

This Grade F flange lock nut with nylon insert addresses critical vibration-induced loosening challenges in automotive assemblies, industrial machinery, and equipment manufacturing. The zinc-plated steel construction provides essential corrosion resistance while maintaining the mechanical integrity required for high-stress applications. The integrated 1/2" flange distributes clamping force over a wider area, reducing surface pressure and preventing damage to connected materials. The UNC coarse thread profile with 10-24 specification ensures rapid installation and reliable performance in applications where fine threads might be susceptible to cross-threading or damage. The nylon insert locking mechanism creates consistent friction against the mating bolt, maintaining preload even under continuous vibration, making it ideal for engines, conveyors, and power transmission systems where fastener integrity is non-negotiable.

Specification Summary & Compliance

This flange lock nut features precise UNC 10-24 coarse threads with Class 2B thread fit tolerance, ensuring compatibility with standard mating components. The external hex drive (3/8" width) facilitates proper torque application using conventional tools. Manufacturing complies with industry standards for Grade F mechanical properties, providing reliable performance in demanding applications. The product meets relevant industrial specifications for zinc-plated steel fasteners and is suitable for applications requiring RoHS and REACH compliance.
