Value Collection B52001611 Hex Lock Nut 7/8-9

Product Description

The VALUE COLLECTION B52001611 is a nylon insert hex lock nut designed to maintain thread engagement under vibration, dynamic loads, and repeated movement. Manufactured from Grade B steel with a zinc finish for basic corrosion resistance, this nut uses an internal nylon collar that deforms against the bolt threads to generate prevailing torque without the need for adhesives or secondary locking hardware. The 7/8-9 UNC thread size makes it a standard choice across structural, mechanical, and equipment-assembly applications. Licensed tradespeople and maintenance technicians working on industrial machinery, structural steel, or mechanical assemblies will find this nut suitable for right-hand threaded fastening work.

This hex lock nut is suited for general-purpose fastening applications that require a reliable locking mechanism in environments subject to vibration or movement. The UNC 7/8-9 thread specification fits standard inch-series bolts and studs. Typical install scenarios include machine frames, brackets, conveyor components, HVAC equipment bases, pump mounts, and similar structural assemblies. The zinc finish provides light corrosion protection appropriate for indoor and moderately exposed environments.

Key Features

• Nylon insert locking style provides prevailing torque without secondary locking compounds
• Grade B steel construction for standard-duty structural and mechanical use
• Zinc finish for basic corrosion resistance in indoor and light-exposure environments
• Right-hand thread direction, UNC standard for compatibility with inch-series fasteners
• Width across flats of 1-1/4 inches accommodates standard wrench and socket tooling

Compatibility

Designed for use with 7/8-9 UNC right-hand threaded bolts and studs in inch-series fastening applications across general mechanical and structural assemblies.

Installation Notes

Installation is performed using a standard 1-1/4 inch wrench or socket. Ensure mating bolt threads are clean and free of debris before installation, as contamination can compromise the nylon insert locking function. Nylon insert lock nuts are generally not recommended for reuse once removed, as the locking element loses prevailing torque after initial installation. Follow applicable industry or equipment manufacturer torque guidelines for the specific joint being assembled.
