Value Collection R50000029 Hex Lock Nut 3/8-24 Nylon Insert

Product Description

The VALUE COLLECTION R50000029 is a 3/8-24 UNF hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert deforms around the mating thread when the nut is driven down, creating resistance to vibration-induced loosening without requiring any secondary locking hardware. At 9/32 inches high and 9/16 inches across the flats, this is a standard-profile hex lock nut suited to fine-thread fastening applications. Plumbers, electricians, HVAC technicians, and general trade mechanics use this type of fastener wherever a secure, reusable threaded connection is needed and vibration or movement is a concern.

This nut is used in light to medium-duty assemblies that call for a 3/8-24 UNF fine-thread fastener. The zinc plating provides a basic level of corrosion resistance appropriate for indoor mechanical assemblies, equipment panels, and bracket work. The right-hand thread direction is standard for the vast majority of fastening applications. The single-piece nylon insert design means no separate lock washer or thread-locking compound is required at installation, which speeds up assembly in the field or shop.

Key Features

• Nylon insert locking style resists vibration-induced loosening without secondary hardware
• 3/8-24 UNF fine-thread specification for precise thread engagement
• Grade 2 steel construction provides adequate strength for light to medium-duty service
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered applications
• Right-hand thread direction matches standard fastener convention
• Compact 9/32 inch height suits space-constrained installations

Compatibility

Designed as a standard 3/8-24 UNF hex lock nut suitable for use wherever a fine-thread nylon insert lock nut of this size is specified in mechanical assemblies.

Installation Notes

Installation requires a standard 9/16 inch wrench or socket. Nylon insert lock nuts are intended to be driven to final torque in one pass — repeated removal and reinstallation degrades the nylon insert and reduces locking effectiveness. Confirm the mating bolt or stud is free of damage and debris before assembly. Follow applicable equipment manufacturer torque specifications for the fastened joint.
