Value Collection B52001659 Hex Lock Nut 1-14 Unf

Product Description

The VALUE COLLECTION B52001659 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener uses a nylon insert locking mechanism that grips the mating thread without requiring adhesives or separate locking hardware. It carries a 1-14 UNF (Unified National Fine) thread size and is built to inch-system standards. The nut stands 35/64 inches high with a width across flats of 1-7/16 inches, making it compatible with standard hex tooling in that size range. Installation is straightforward with a wrench or socket set.

This hex lock nut is suited for general mechanical assembly applications where vibration resistance is required. The fine thread pitch of the 1-14 designation provides stronger thread engagement per unit length compared to coarse thread variants, making it appropriate for precision assemblies, structural connections, and equipment requiring secure fastening under cyclic loading. It is commonly used in industrial equipment maintenance, mechanical fabrication, and trade-service repair work across HVAC, plumbing support structures, and electrical equipment mounting applications.

Key Features

• Nylon insert locking style resists loosening from vibration without adhesives
• 1-14 UNF fine thread for stronger thread engagement and precise fitment
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments
• Right-hand thread direction — standard for most mechanical assemblies
• Width across flats of 1-7/16 inches compatible with standard hex tooling

Compatibility

Designed as a standard inch-system replacement or service fastener for any assembly requiring a 1-14 UNF nylon insert hex lock nut in Grade 2 steel.

Installation Notes

Turn off and de-energize any equipment before replacing fasteners on live mechanical assemblies. Use a correctly sized wrench or socket matched to the 1-7/16 inch across-flats dimension to avoid rounding the nut. Nylon insert lock nuts are generally single-use — once the nylon has been deformed by threading, reuse may reduce locking effectiveness. Follow applicable mechanical or structural codes for torque requirements specific to the assembly.
