Value Collection R52001654 Hex Lock Nut Nylon Insert Grade 2

Product Description

The VALUE COLLECTION R52001654 is a nylon insert hex lock nut designed to resist vibration-induced loosening in threaded fastener assemblies. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut features a nylon insert locking style that grips the mating bolt thread without requiring adhesives or deforming the fastener. It measures 3/16 inches in height with a width across flats of 11/32 inches and follows a right-hand UNC thread direction. It is sized and toleranced for inch-system fastener applications and is installed by electricians, plumbers, HVAC technicians, and general trades when secure, reusable thread retention is needed.

This hex lock nut is suited for residential and light commercial mechanical assemblies where thread security under vibration or thermal cycling is a concern. Typical applications include equipment mounting, panel assemblies, ductwork hardware, and general-purpose structural connections using UNC-threaded fasteners in inch-measurement systems. The zinc plating provides a functional protective coating for indoor and mildly corrosive environments.

Key Features

• Nylon insert locking style resists loosening from vibration without damaging mating threads
• Grade 2 steel construction provides adequate strength for general fastening applications
• Zinc-plated finish offers basic corrosion protection for indoor and lightly exposed environments
• Right-hand UNC thread direction for compatibility with standard inch-system fasteners
• Width across flats of 11/32 inches fits standard hex drivers and wrenches
• Minimum order quantity of 100 units makes it practical for bulk trade use

Compatibility

Designed as a general-purpose replacement or stocking nut for UNC inch-system threaded fastener assemblies requiring nylon insert locking in Grade 2 steel with zinc plating.

Installation Notes

Install using a standard hex wrench or socket sized for 11/32 inches across flats. De-energize or shut down any equipment before servicing fastener assemblies in electrical or mechanical panels. Nylon insert lock nuts are intended for reuse in low-cycle applications but should be inspected and replaced if the nylon insert shows signs of wear or deformation. Follow applicable mechanical and structural codes for the specific trade application.
