Value Collection R50000013 Hex Lock Nut 1/4-28 Unf

Product Description

The VALUE COLLECTION R50000013 is a 1/4-28 UNF hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert deforms around mating threads under torque to create resistance against loosening from vibration or rotation. At 19/64 inches high and 7/16 inches across the flats, this fastener fits standard hex tooling. The zinc plating provides a baseline level of corrosion resistance for general indoor and light-duty applications. Right-hand thread direction follows standard UNF convention. This nut is appropriate for use by mechanics, electricians, HVAC technicians, plumbers, and general trade installers working with 1/4-28 UNF fastener assemblies.

This hex lock nut is suited for light mechanical assemblies, equipment panels, brackets, and enclosures where vibration resistance is required without the need for thread-locking compound. The 1/4-28 UNF thread is a fine-pitch series commonly used in automotive, HVAC, electrical enclosure, and general equipment fabrication applications. The nylon insert provides a reusable locking action under normal installation conditions. Grade 2 steel construction makes this nut appropriate for low-to-medium clamp load applications where high-strength fasteners are not required.

Key Features

• Nylon insert locking style resists loosening under vibration without thread-locking compounds
• 1/4-28 UNF fine-pitch thread for precise fastening in standard applications
• Grade 2 steel construction for general-duty clamp loads
• Zinc-plated finish provides baseline corrosion resistance
• Right-hand thread direction follows standard UNF convention
• 7/16 inch width across flats fits standard hex wrenches and sockets

Compatibility

Designed for use with any 1/4-28 UNF male-threaded fastener or stud in general mechanical, HVAC, electrical, or plumbing equipment assemblies requiring nylon insert vibration-resistant locking nuts.

Installation Notes

Install using a standard 7/16 inch hex wrench or socket driver. Nylon insert lock nuts are designed for one primary installation; reuse after removal is possible but locking effectiveness may decrease. Do not exceed the torque capacity appropriate for Grade 2 steel fasteners at this thread size. Ensure mating threads are clean and free of debris before installation to prevent galling or cross-threading.
