Value Collection C50000406 Serrated Flange Nut 1/4-20 Zinc

Product Description

The VALUE COLLECTION C50000406 is a serrated flange nut with a 1/4-20 unified coarse thread, manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The integrated serrated flange distributes clamping load across a wider bearing surface while the teeth bite into the mating material to resist loosening under vibration. The flange diameter measures 0.703 inches and the overall height measures 0.236 inches. These nuts are sold in a pack of 100 and are installed by electricians, HVAC technicians, plumbers, and general mechanical trades wherever a self-locking, load-spreading fastener is required in light-duty assemblies.

Serrated flange nuts in 1/4-20 are commonly used in HVAC equipment panels, electrical enclosures, plumbing fixture brackets, and sheet metal assemblies. The serrations eliminate the need for a separate lock washer in most applications, reducing parts count and installation time. These are suitable for indoor and protected outdoor installations where mild corrosion resistance from the zinc plating is sufficient for the service environment.

Key Features

• Integrated serrated flange eliminates the need for a separate lock washer
• 1/4-20 unified coarse thread for broad tool and hardware compatibility
• Grade 2 steel construction provides adequate strength for light-duty fastening applications
• Zinc-plated finish offers basic corrosion resistance in dry or protected environments
• Flange diameter of 0.703 inches distributes clamp load over a wider bearing area
• Pack of 100 supports production, service fleet, and shop stock applications

Compatibility

Designed as a standard 1/4-20 inch serrated flange nut suitable for use in any application requiring a unified coarse thread fastener with an integrated locking flange in Grade 2 steel.

Installation Notes

Install using a wrench or socket sized to the 0.428 to 0.438 inch across-flats dimension. Ensure the serrated face seats directly against the mating surface for the locking feature to function correctly. Do not install the serrated flange against a hardened or plated surface that may prevent the teeth from engaging. Follow applicable mechanical or electrical codes for torque and fastener grade requirements in the specific assembly.
