Value Collection R52000918 Serrated Flange Nut 8-32

Product Description

The VALUE COLLECTION R52000918 is a serrated flange nut in 8-32 thread size, manufactured from Grade 2 steel with a zinc-plated finish. The integrated serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. The flange diameter measures 0.469 inches and the flange height is 0.203 inches. This fastener is suited for light-duty mechanical and electrical panel assemblies where a built-in locking action and load-spreading flange eliminate the need for a separate washer.

This serrated flange nut is used in general-purpose fastening applications across HVAC equipment, electrical enclosures, light structural assemblies, and sheet metal fabrication. It is appropriate for both production assembly and field service work wherever an 8-32 threaded fastener is required with vibration resistance built into the nut profile. Installation is performed by hand and power tool, making it a straightforward component for trade professionals and maintenance technicians.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• Grade 2 steel construction suitable for light-duty mechanical and panel applications
• Zinc-plated finish provides basic corrosion resistance in dry indoor environments
• Flange diameter of 0.469 inches distributes clamping load over a wider bearing area
• Hardness rated Rockwell HR15N 78-90 for consistent performance in production and field use
• Inch measurement system with 8-32 thread for compatibility with standard UNC fastener hardware

Compatibility

Designed as a standard 8-32 UNC serrated flange nut for use with any 8-32 threaded bolt or stud in light-duty mechanical, electrical, or sheet metal assemblies.

Installation Notes

Installation is performed using a standard wrench sized to the 0.334 to 0.344 inch width-across-flats dimension. Ensure the serrated face seats flush against the mating surface to allow the serrations to engage properly. Power down any electrical assembly before installing or removing fasteners in live panels in accordance with applicable NFPA 70 lockout-tagout procedures. Do not over-torque; Grade 2 fasteners have lower proof load limits than Grade 5 or Grade 8 hardware.
