Value Collection R50000015 Hex Lock Nut 3/8-24 Unf

Product Description

The VALUE COLLECTION R50000015 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. It uses a nylon insert collar that deforms around mating threads to create a friction-based locking action without the need for thread-locking compounds or secondary hardware. The nut is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in standard indoor and light-duty applications. The 3/8-24 UNF thread size indicates a fine-thread specification, which is common in mechanical assemblies requiring precise clamping and load distribution. Licensed mechanics, millwrights, and maintenance technicians working on equipment assemblies are the typical installers of this fastener.

This lock nut is suited for use in general mechanical, HVAC equipment, and light industrial assemblies where a UNF 3/8-24 thread pattern is specified. The fine thread pitch makes it a common choice in sheet-metal equipment frames, fan assemblies, motor mounting hardware, and similar trade applications where vibration resistance is a requirement. It measures 15/32 inches in height and 9/16 inches across the flats, fitting standard 9/16-inch wrenches. The zinc-plated finish is appropriate for interior or protected environments.

Key Features

• Nylon insert locking style provides vibration-resistant clamping without thread-locking compounds
• 3/8-24 UNF fine-thread specification for precise load distribution
• Grade 2 steel construction with zinc-plated finish for standard corrosion protection
• Right-hand thread direction per standard UNF fastener convention
• 9/16-inch width across flats fits common wrench and socket sizes
• 15/32-inch height suitable for standard hex lock nut seating depths

Compatibility

Designed as a standard UNF nylon insert hex lock nut for use in any assembly specifying a 3/8-24 right-hand thread fastener.

Installation Notes

Installation requires a standard 9/16-inch open-end or box wrench and a compatible 3/8-24 UNF fastener. Ensure mating bolt and receiving surface threads are clean and free of damage before seating the nut. Nylon insert lock nuts are generally rated for single use — once the nylon insert has been fully engaged, reuse may reduce locking effectiveness.
