Value Collection R63482920 Serrated Flange Nut 1/4-28

Product Description

The VALUE COLLECTION R63482920 is a serrated flange nut with a 1/4-28 unified fine thread and a nominal flange diameter of 0.594 inches. The integrated serrated flange acts as a built-in locking washer, distributing clamping load across the flange face while the serrations bite into the mating surface to resist vibration-induced loosening. Manufactured from 18-8 stainless steel, this nut resists corrosion in wet, outdoor, and mildly chemical environments. Licensed plumbers, electricians, HVAC technicians, and general trade mechanics use this fastener where a standard hex nut and separate lock washer would otherwise be required.

This serrated flange nut is suited for light structural, panel, enclosure, and equipment-mounting applications across residential and commercial trade work. The fine 1/4-28 thread pitch provides precise torque control and is commonly used in applications requiring a secure fit in thin or tapped-metal assemblies. The 18-8 stainless steel construction makes it appropriate for installations exposed to moisture or corrosive conditions where carbon steel hardware is unsuitable.

Key Features

• Integrated serrated flange provides vibration resistance without a separate lock washer
• 1/4-28 unified fine thread for precise engagement and controlled clamping
• 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Flange distributes clamping load to protect soft or thin mating surfaces
• Flange height of 0.236 inches with minimum height of 0.222 inches for consistent seating

Compatibility

Designed as a standard 1/4-28 serrated flange nut suitable for use with any 1/4-28 threaded fastener application requiring an integrated locking flange in 18-8 stainless steel.

Installation Notes

Install using a wrench sized to the 0.428 to 0.438 inch width-across-flats dimension. Ensure the serrated face seats flush against the mating surface for proper locking action. Power down or de-energize any equipment before accessing fastener locations on electrical or HVAC enclosures. Do not use with mating surfaces that cannot accept the bite of the serrations, such as soft plastics or coated finishes requiring marring-free contact.
