Value Collection HFNFI2-100-100B Serrated Flange Nut 10-32

Product Description

The VALUE COLLECTION HFNFI2-100-100B is a serrated flange nut designed for secure fastening in general mechanical and structural applications. The integrated serrated flange distributes clamping load over a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut carries a 10-32 unified fine thread and a flange diameter of 0.50 inches. It is commonly installed by HVAC technicians, electricians, plumbers, and general mechanical trades wherever a self-locking flange nut is called for in light-duty assemblies.

This serrated flange nut is suited for residential and light commercial equipment panels, electrical enclosures, sheet metal assemblies, and mechanical equipment where vibration resistance is needed without a separate lock washer. The 10-32 thread size makes it a common choice for equipment cabinets, control panel hardware, and general machine fastening. The zinc plating provides a serviceable level of protection in indoor and sheltered environments.

Key Features

• Serrated flange eliminates the need for a separate lock washer and resists loosening under vibration
• 10-32 unified fine thread for precision engagement in tapped holes and threaded assemblies
• Grade 2 steel construction provides adequate strength for light-duty mechanical applications
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered installations
• Flange diameter of 0.50 inches distributes clamping load across a wider bearing surface
• Width across flats up to 0.375 inches for standard hex-drive tooling

Compatibility

Designed as an OEM-style replacement or standard hardware addition for assemblies using 10-32 threaded fasteners requiring a serrated flange nut with a 0.50-inch flange diameter.

Installation Notes

Install using a standard hex driver or wrench sized to the 0.375-inch across-flats dimension. Ensure the mating threaded fastener or stud is clean and free of debris before engagement. De-energize and lock out all electrical or mechanical equipment before servicing any hardware within live panels or enclosures. Do not exceed the torque range appropriate for Grade 2 steel 10-32 fasteners as specified by applicable equipment service documentation.
