Value Collection R63482368 Serrated Flange Nut 1/4-20

Product Description

The VALUE COLLECTION R63482368 is a serrated flange nut in 1/4-20 thread, manufactured from 18-8 stainless steel. 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 0.594 inches and the overall nut height reaches 0.236 inches. This fastener is suitable for trade and industrial assembly work where a separate lock washer would otherwise be required, reducing hardware count and speeding installation in corrosion-prone environments.

Serrated flange nuts in 1/4-20 thread are used across a broad range of mechanical and structural assembly applications including HVAC equipment panels, electrical enclosures, plumbing fixture brackets, and light structural frames. The 18-8 stainless steel construction makes this nut appropriate for indoor and outdoor installations where moisture, mild chemicals, or humidity are present. Installers in HVAC, electrical, plumbing, and general mechanical trades will find this nut applicable wherever a 1/4-20 threaded fastener with locking capability is required.

Key Features

• Serrated flange provides integrated vibration resistance without a separate lock washer
• 18-8 stainless steel construction resists corrosion in wet and humid environments
• Flange diameter of 0.594 inches distributes clamping load over a wider bearing area
• 1/4-20 UNC thread for compatibility with standard inch-series fastener systems
• Compact flange height of 0.236 inches suits installations with limited clearance
• Inch measurement system; consistent dimensional tolerances across width-across-flats range of 0.428 to 0.438 inches

Compatibility

Designed as a standard inch-series serrated flange nut for use with any 1/4-20 UNC threaded bolt, stud, or screw in mechanical and structural assembly applications.

Installation Notes

Installation is performed by hand-starting the nut onto a 1/4-20 threaded fastener and tightening with a wrench sized for the 0.428 to 0.438 inch across-flats dimension. Power down or de-energize any equipment before fastening components in electrical or HVAC enclosures. The serrated flange is designed to seat against a flat, clean mating surface for maximum locking effectiveness; avoid installing against painted or coated surfaces where the serrations cannot fully engage. Follow applicable codes such as the NEC or IFGC for fastener requirements specific to the installation type.
