Value Collection B52001610 Hex Lock Nut 7/8-14 Unf

Product Description

The VALUE COLLECTION B52001610 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade B steel with a zinc finish for basic corrosion resistance, this fastener carries a 7/8-14 UNF right-hand thread. The nylon insert collar compresses against the mating thread to create a prevailing torque lock without the need for adhesives or secondary locking hardware. At 63/64 inches tall with a 1-1/4 inch width across flats, this nut fits standard 7/8-inch UNF fastener assemblies across a broad range of mechanical and structural applications. Licensed tradespeople and assembly technicians install this type of fastener in equipment, machinery, and structural connections where vibration resistance is required.

This hex lock nut is suited for use in industrial assemblies, mechanical equipment, vehicle components, and structural connections requiring a reliable prevailing-torque fastener. The 7/8-14 UNF thread pitch is a fine-thread designation, making it appropriate for applications where greater thread engagement per inch and finer torque control are priorities. It is sold individually with a minimum order quantity of 5 units.

Key Features

• Nylon insert locking style provides prevailing torque resistance without adhesives
• Grade B steel construction for standard mechanical strength requirements
• Zinc finish provides basic corrosion protection for indoor and sheltered environments
• 7/8-14 UNF fine-thread specification for precise thread engagement
• Right-hand thread direction per standard UNF fastener convention
• Width across flats of 1-1/4 inches fits standard open-end and socket wrenches

Compatibility

Designed for use with 7/8-14 UNF right-hand threaded bolts and studs conforming to inch-system fastener standards. Meets UNF fastener dimensional standards; does not meet military specifications.

Installation Notes

Installation requires a standard open-end, box-end, or socket wrench sized for a 1-1/4 inch hex. Power down or de-energize any equipment before accessing fastener locations on machinery. Nylon insert lock nuts are generally considered single-use; once the nylon insert has been fully threaded and removed, the prevailing torque may be reduced on reinstallation. Consult applicable equipment service documentation and relevant mechanical codes for torque requirements specific to the assembly.
