Value Collection R52000872 Serrated Flange Nut 6-32 Zinc

Product Description

The VALUE COLLECTION R52000872 is a serrated flange nut in a 6-32 thread size, manufactured from Grade 2 steel with a zinc-plated finish. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. The flange diameter measures 0.422 inches and the flange height is 0.171 inches. This fastener is installed by electricians, HVAC technicians, sheet metal fabricators, and general mechanical trades wherever a compact, vibration-resistant nut is needed in light-duty steel assemblies.

This serrated flange nut is suited for residential and light commercial applications involving panel enclosures, electrical boxes, equipment frames, ductwork, and similar thin-gauge steel or sheet metal assemblies. The 6-32 thread is a common machine screw size found throughout electrical and mechanical equipment. The serrations eliminate the need for a separate lock washer in most standard installations, reducing part count and assembly time.

Key Features

• Serrated flange locks against the mating surface to resist vibration-induced loosening without a separate washer
• Grade 2 steel construction suitable for general-purpose light-duty fastening
• Zinc-plated finish provides basic corrosion resistance in indoor environments
• Flange diameter of 0.422 inches distributes load across a wider bearing area
• Hardness rated 78-90 HR15N for consistent performance in standard machine screw applications
• 6-32 thread size compatible with widely available standard machine screws

Compatibility

Designed as a general-purpose replacement or stocking fastener for 6-32 machine screw applications in electrical enclosures, equipment panels, and light sheet metal assemblies.

Installation Notes

Install with standard hand tools sized for a 0.302 to 0.312 inch width-across-flats hex. Ensure the serrated flange face seats flush and squarely against the mating surface to achieve full locking engagement. Do not reuse serrated flange nuts after removal, as the serrations may be deformed and locking effectiveness will be reduced. Follow applicable NEC or equipment manufacturer torque guidelines for the assembly being serviced.
