Gibraltar CN-0SS-G Flange Nut 1/4-20 303 Stainless Steel

Product Description

The GIBRALTAR CN-0SS-G is a 1/4-20 threaded flange nut machined from Grade 303 stainless steel. The integrated flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer in many fastening applications. The nut measures 5/16 inches in height with a 5/8 inch flange diameter, a 3/32 inch flange height, and 1/2 inch across the flats for standard wrench engagement. Grade 303 stainless provides solid corrosion resistance and machinability, making this fastener suitable for mechanical assemblies, equipment panels, and light structural connections in demanding environments.

This flange nut is used across a wide range of trade and industrial applications including HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and general mechanical maintenance. The 1/4-20 unified coarse thread is one of the most common fastener standards in North American trade work. This nut is appropriate for both original equipment assembly and field repair work performed by HVAC technicians, plumbers, electricians, and maintenance professionals who require a corrosion-resistant fastening solution.

Key Features

• 1/4-20 unified coarse thread for broad compatibility with standard hardware
• Grade 303 stainless steel construction for corrosion resistance in wet or humid environments
• Integrated flange bearing surface eliminates the need for a separate washer in many applications
• 5/8 inch flange diameter spreads clamping load across a wider area
• 1/2 inch across flats for engagement with standard 1/2 inch wrenches and sockets
• Inch measurement system for direct compatibility with standard North American fastener tooling

Compatibility

Designed as a standard 1/4-20 flange nut for use in mechanical assemblies, equipment enclosures, and general fastening applications that require a corrosion-resistant inch-series nut with an integrated bearing flange.

Installation Notes

Installation is performed with a standard 1/2 inch wrench or socket. Ensure mating threads are clean and free of debris before assembly. Power down or depressurize any system before accessing fastened components during service or repair. Do not exceed the load rating of the mating hardware or substrate material.
