Value Collection HFNI2-100-100BX Serrated Flange Nut 10-24

Product Description

The VALUE COLLECTION HFNI2-100-100BX is a serrated flange nut with a 10-24 UNC thread and a 1/2-inch flange diameter. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Manufactured from Grade 2 steel with a zinc-plated finish, this nut suits general-purpose fastening in mechanical assemblies, sheet metal work, and equipment fabrication. The flange height measures 0.219 inches and the maximum height is also 0.219 inches. Licensed tradespeople and skilled assemblers install these in light structural, electrical enclosure, and mechanical panel applications.

These serrated flange nuts are suited for standard inch-series fastening applications where vibration resistance is needed without a separate lock washer. The 10-24 thread size is common in light-gauge sheet metal panels, electrical enclosures, HVAC equipment cabinets, and general mechanical assemblies. The zinc-plated finish provides baseline corrosion resistance appropriate for indoor and protected outdoor environments. Sold in multiples of 100, this SKU is well-suited for shop stock, service van inventory, and production assembly use.

Key Features

• Serrated flange design locks against vibration without a separate washer
• 10-24 UNC thread — common size for light-gauge sheet metal and electrical panel fastening
• Grade 2 steel construction provides reliable tensile strength for general-purpose use
• Zinc-plated finish for corrosion resistance in indoor and protected environments
• Flange diameter of 0.480 to 0.500 inches spreads load across the bearing surface
• Minimum order quantity of 100 pieces supports bulk stocking and production use

Compatibility

Designed as an OEM-style replacement or service-stock fastener compatible with any standard 10-24 UNC threaded fastening application requiring a serrated flange nut in the inch measurement system.

Installation Notes

Installation is performed by mechanics, electricians, and HVAC technicians using standard hand tools or a nut driver sized to the 0.365 to 0.375-inch width across flats. De-energize all electrical circuits before fastening hardware inside live panels or enclosures, per NEC requirements. The serrated flange should seat directly against the mating surface — do not stack additional washers between the flange and the workpiece, as this defeats the anti-loosening function. Inspect the mating surface for burrs or debris that could prevent full flange contact.
