Value Collection NLI2062NTU-010B Hex Lock Nut 5/8-11

Product Description

The VALUE COLLECTION NLI2062NTU-010B is a 5/8-11 hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a bright uncoated finish. The nylon insert compresses against the bolt thread when torqued, creating friction that resists loosening from vibration and dynamic loads without damaging the mating thread. At 39/64 inches in height and 1-1/16 inches across the flats, this nut conforms to ASME B 18.16.6 standards and uses a right-hand UNC thread form. It is a standard fastener used across mechanical, structural, and equipment-assembly applications in HVAC, plumbing, electrical, and general trade work.

This nut is suited for residential and light commercial applications where a reusable, prevailing-torque locking fastener is needed on a 5/8-11 threaded bolt or stud. Common install scenarios include equipment mounting, bracket assemblies, pipe hangers, and structural connections subject to vibration. The nylon insert remains effective through multiple installation and removal cycles under normal service conditions, making it a practical choice for field technicians assembling or servicing mechanical equipment.

Key Features

• Nylon insert locking style resists loosening under vibration without thread damage
• 5/8-11 UNC right-hand thread for broad fastener compatibility
• Grade 2 steel construction suitable for general-purpose structural and mechanical use
• Bright uncoated finish — 39/64 inches height, 1-1/16 inches width across flats
• Conforms to ASME B 18.16.6 dimensional and performance standards
• Reusable insert design supports multiple removal and reinstallation cycles

Compatibility

Designed as a general-purpose replacement or new-installation hex lock nut for any 5/8-11 UNC threaded fastener application requiring a prevailing-torque nylon insert nut per ASME B 18.16.6.

Installation Notes

Installation is performed by hand and with standard open-end, combination, or socket wrenches sized for a 1-1/16 inch hex. Ensure the mating bolt or stud is free of debris and damage before threading the nut. Do not use an impact driver at full torque setting, as excessive speed can degrade the nylon insert. Always consult the equipment manufacturer or applicable structural code for required torque values on the specific assembly.
