Value Collection B52001658 Hex Lock Nut 7/8-9 Nylon Insert

Product Description

The VALUE COLLECTION B52001658 is a 7/8-9 hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert deforms around the mating thread when the nut is driven down, creating resistance to vibration-induced loosening without requiring a separate locking device. At 15/32 inches high and 1-1/4 inches across the flats, this nut follows standard UNC thread geometry with right-hand thread direction. It is sold individually and is appropriate for general mechanical assembly work across maintenance, construction, and light fabrication applications.

This nut is suited for non-critical fastening applications in residential and commercial construction, equipment maintenance, and general industrial assembly where a UNC 7/8-9 fastener is required. The zinc plating provides basic corrosion resistance in dry or mildly humid environments. Grade 2 steel is appropriate for standard load-bearing connections that do not require the higher proof load of Grade 5 or Grade 8 hardware. Tradespeople and maintenance technicians use this nut as a replacement or new-installation fastener in structural framing, equipment mounting, and similar field assembly tasks.

Key Features

• Nylon insert locking style resists loosening from vibration without adhesives or additional hardware
• Grade 2 steel construction suitable for general-purpose fastening applications
• Zinc-plated finish provides basic corrosion resistance in standard service environments
• Right-hand UNC thread direction conforms to standard inch-series fastener practice
• Compact 15/32-inch height fits tight clearance applications

Compatibility

Designed as a standard UNC replacement or new-installation hex lock nut for any 7/8-9 threaded bolt or stud in general mechanical and structural assembly applications.

Installation Notes

Installation is performed by hand with a standard 1-1/4-inch wrench or socket. Drive the nut down until the nylon insert engages the bolt threads, then torque to values appropriate for Grade 2 steel fasteners per applicable project specifications. Nylon insert lock nuts are generally considered single-use; inspect the insert before reuse and replace if the nylon shows wear or deformation. No special tools or trade licenses are required for standard fastener installation.
