Value Collection B52001613 Hex Lock Nut 1-8 Unc

Product Description

The VALUE COLLECTION B52001613 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade B steel with a zinc-plated finish for corrosion resistance, this fastener uses an interference-fit nylon insert to grip threads and maintain clamp load without secondary locking hardware. The nut follows UNC (Unified National Coarse) thread standards at a 1-8 thread size and features right-hand thread direction. It measures 1-3/64 inches in height with a width across flats of 1-7/16 inches. Licensed electricians, plumbers, HVAC technicians, pipefitters, and general mechanical contractors regularly use nylon insert lock nuts where vibration resistance is required in structural and equipment mounting applications.

This hex lock nut is suited for use in residential and commercial construction, mechanical equipment assemblies, structural connections, and utility installations where a reliable, reusable locking fastener is required. The zinc plating provides a base level of corrosion protection appropriate for indoor and moderately exposed environments. The nylon insert engages the mating bolt threads without damaging them, making the nut suitable for applications that may require periodic disassembly and reassembly.

Key Features

• Nylon insert locking style resists loosening from vibration without additional locking hardware
• Grade B steel construction provides standard mechanical strength for UNC fastener applications
• Zinc-plated finish offers corrosion resistance for general indoor and sheltered use
• Right-hand UNC thread at 1-8 conforms to standard inch-series fastener specifications
• Width across flats of 1-7/16 inches accepts standard open-end and socket wrenches
• Reusable design allows disassembly without damaging mating bolt threads

Compatibility

Designed for use with 1-inch nominal diameter UNC (Unified National Coarse) Grade B threaded fasteners in standard inch-series assemblies.

Installation Notes

Installation requires a standard open-end or socket wrench sized to the 1-7/16 inch width across flats. Confirm that the mating bolt thread specification matches UNC 1-8 before installation. Nylon insert lock nuts should be run down by hand to verify thread engagement before applying torque. Do not exceed the rated mechanical load for Grade B steel fasteners, and replace any nut showing visible wear to the nylon insert.
