Value Collection R63482844 Serrated Flange Nut 5/16-18

Product Description

The VALUE COLLECTION R63482844 is a serrated flange nut in 5/16-18 unified coarse 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 0.68 inches and the overall nut height is 0.283 inches. These fasteners are installed by mechanical contractors, HVAC technicians, electricians, plumbers, and general maintenance trades wherever a self-locking flange nut is required in a corrosion-resistant application.

This nut is suited for residential and light commercial mechanical assemblies, equipment panels, enclosures, brackets, and structural connections where vibration resistance and corrosion resistance are both priorities. The 18-8 stainless steel grade performs well in wet, humid, and mildly corrosive environments, making it a practical choice for outdoor equipment, pool and spa hardware, plumbing support brackets, and HVAC unit assemblies. These nuts are sold individually but carry a minimum order quantity of 100 pieces per order.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• 18-8 stainless steel construction resists corrosion in wet and humid environments
• 5/16-18 unified coarse thread for broad fastener compatibility
• Flange diameter of 0.68 inches spreads clamping load over a larger bearing area
• Compact flange height of 0.283 inches suits tight clearance applications
• Width across flats up to 0.500 inches fits standard SAE hex tooling

Compatibility

Designed as a standard 5/16-18 serrated flange nut suitable for use with any 5/16-18 UNC threaded fastener or stud where an integrated locking flange is required.

Installation Notes

Install using a standard 1/2-inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before assembly. Power down or de-energize any equipment before accessing fastener locations on electrical or mechanical assemblies. Do not use impact drivers at full torque on stainless steel fasteners, as galling of the threads can occur at high rotational speeds.
