Value Collection R63223283 Hex Lock Nut 18-8 Ss Nylon Insert

Product Description

The VALUE COLLECTION R63223283 is a nylon insert hex lock nut made from 18-8 stainless steel. It measures 3/16 inches high with a width across flats of 5/16 inches and uses a right-hand UNC thread. The nylon insert creates a friction-based locking action that resists loosening from vibration and movement without requiring thread-locking compounds. The 18-8 stainless steel construction provides good corrosion resistance in general industrial, plumbing, and mechanical applications. This fastener is sold individually and ordered in multiples of 100.

This nut is suited for light-duty mechanical assemblies, plumbing fixtures, HVAC equipment panels, and electrical enclosure hardware where corrosion resistance and vibration resistance are required. The inch-system UNC thread pattern makes it compatible with standard fractional-size fastener systems used across residential and commercial trade work. Typical installers include plumbers, HVAC technicians, electricians, and general mechanical contractors working on equipment requiring stainless fasteners in wet or corrosive environments.

Key Features

• Nylon insert locking style resists loosening under vibration without adhesives
• 18-8 stainless steel grade provides corrosion resistance for wet and outdoor environments
• 3/16 inch height keeps the installed profile compact in tight assemblies
• 5/16 inch width across flats fits standard fractional wrenches and sockets
• Right-hand UNC thread conforms to inch-system fastener standards
• Does not meet military specifications — suited for commercial and industrial use

Compatibility

Designed as a standard inch-system UNC nylon insert hex lock nut for use with matching fractional-size bolts and studs in general mechanical, HVAC, plumbing, and electrical assembly applications.

Installation Notes

Installation requires a wrench or socket sized to the 5/16 inch width across flats. Power down or de-energize any equipment before replacing fasteners on live assemblies. The nylon insert is a single-use locking element — once fully seated and removed, the locking torque is reduced, so replacement with a new nut is recommended after disassembly. Follow applicable codes and equipment manufacturer torque guidance for the specific assembly.
