Value Collection B52001684 Hex Lock Nut 7/8-9 Nylon Insert

Product Description

The VALUE COLLECTION B52001684 is a 7/8-9 hex lock nut with a nylon insert locking style, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert creates interference with the mating thread, resisting loosening caused by vibration and torque. At 15/32 inches high with a 1-1/4 inch width across flats, this fastener follows Unified National Coarse (UNC) thread standards and a right-hand thread direction. It is a practical, utility-grade hardware component suited for general mechanical assembly and structural fastening applications across HVAC, plumbing, electrical, and equipment installation work.

This hex lock nut is used in residential and commercial trade applications wherever a reliable, reusable locking fastener is required. The zinc plating provides a basic level of corrosion resistance suitable for indoor and moderately exposed environments. Technicians and installers working on equipment mounting, panel assembly, ductwork framing, and structural bracketing will find this a standard-fit fastener for 7/8-9 threaded rod and bolt connections. Each unit is sold individually with a minimum order quantity of 25 pieces.

Key Features

• Nylon insert locking mechanism resists loosening under vibration and dynamic loads
• Grade 2 steel construction for general-purpose fastening applications
• Zinc-plated finish provides basic corrosion resistance
• UNC 7/8-9 thread specification with right-hand thread direction
• 15/32 inch height and 1-1/4 inch width across flats for standard wrench fitment

Compatibility

Designed as a general-purpose UNC hex lock nut for use with 7/8-9 threaded fasteners in standard inch-measurement mechanical and structural assembly applications.

Installation Notes

Installation requires a standard open-end or combination wrench sized to 1-1/4 inch across flats. Shut down and de-energize any associated equipment before performing fastener work near electrical or mechanical components. The nylon insert is designed for single-use locking performance; reuse may reduce locking effectiveness. Follow applicable mechanical and structural codes for torque and fastener-grade requirements specific to the assembly.
