Value Collection B52001672 Hex Lock Nut 7/8-9 Grade 8

Product Description

The VALUE COLLECTION B52001672 is a 7/8-9 hex lock nut with a nylon insert locking style, manufactured from Grade 8 steel with a zinc yellow dichromate finish. The nylon insert grips the mating thread to resist loosening caused by vibration and torque, making this nut suitable for high-load fastening applications. At 63/64 inches in height with a 1-1/4 inch width across flats, it fits standard 7/8-9 UNC threaded fasteners. Installers in heavy equipment, industrial fabrication, structural assembly, and mechanical maintenance use this nut where positive thread retention is required under dynamic loading conditions.

This hex lock nut is intended for use with 7/8-9 UNC right-hand threaded bolts and studs. It is commonly applied in structural steel connections, machinery frames, agricultural equipment, and commercial vehicle assemblies where Grade 8 strength and reliable anti-loosening performance are required. The zinc yellow dichromate finish provides corrosion resistance suitable for general industrial environments. This nut is sold individually with a minimum order quantity of 5 pieces.

Installation Notes

Installation is performed with a standard 1-1/4 inch hex wrench or socket. Confirm the mating bolt thread size and pitch match 7/8-9 UNC before installation. Nylon insert lock nuts are generally intended for single-use applications, as reuse can reduce the locking effectiveness of the nylon element. Power down or de-energize any equipment before accessing fastener locations in live mechanical or electrical assemblies.
