Value Collection R52001652 Hex Lock Nut 1/4 in Unc

Product Description

The VALUE COLLECTION R52001652 is a hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert collar deforms around mating threads during installation, creating prevailing torque that resists loosening from vibration and thermal cycling. At 0.125 inches high with a 1/4-inch width across flats, this compact fastener is sized for tight assemblies where space is limited. It follows UNC thread standards with a right-hand thread direction, making it compatible with standard inch-series fastener tooling. Installed by millwrights, maintenance technicians, HVAC mechanics, plumbers, and electricians in a wide range of mechanical assemblies.

This hex lock nut is suited for general-purpose mechanical, electrical, and plumbing applications where vibration resistance is required without chemical thread-locking compounds. Typical use cases include equipment panels, bracket assemblies, conduit fittings, and light structural connections in both residential and commercial settings. The zinc plating provides basic corrosion resistance for indoor and protected outdoor environments. It is not intended for high-temperature applications where nylon insert integrity may be compromised.

Key Features

• Nylon insert locking style provides prevailing torque without adhesives or additional hardware
• Grade 2 steel construction suitable for general-purpose fastening loads
• Zinc-plated finish offers basic corrosion resistance in dry or protected environments
• UNC thread standard for compatibility with standard inch-series bolts and studs
• Right-hand thread direction follows conventional installation tooling
• Compact 0.125-inch height fits space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or general-use hex lock nut for standard UNC inch-series threaded fastener applications across mechanical, electrical, and plumbing assemblies.

Installation Notes

Installation is performed by the applicable licensed trade or maintenance technician using a standard hex wrench or socket matching the 1/4-inch across-flats dimension. De-energize electrical systems and relieve system pressure before replacing fasteners in live assemblies. Nylon insert lock nuts are single-use by design and should not be reused after removal, as the insert loses prevailing torque after the first installation. Follow applicable code requirements, including NEC for electrical enclosures, IPC for plumbing assemblies, or IFGC for gas piping bracket connections, as appropriate to the application.
