Value Collection B52001629 Hex Lock Nut 7/8-14 Grade 8

Product Description

The VALUE COLLECTION B52001629 is a 7/8-14 UNF hex lock nut with a nylon insert locking style, manufactured from Grade 8 steel with a yellow zinc dichromate finish. The nylon insert creates prevailing torque that resists loosening under vibration and dynamic loads, making this nut a reliable choice for high-strength fastening applications. It measures 63/64 inches in height and 1-1/4 inches across the flats, following standard inch-series dimensions. The right-hand thread direction is consistent with the vast majority of threaded fastener assemblies. Installation is straightforward for mechanics, maintenance technicians, and anyone working with Grade 8 inch-series fasteners.

This nut is suited for use in mechanical assemblies, heavy equipment, agricultural machinery, automotive drivetrain components, and industrial fabrication where a fine-thread, high-strength prevailing-torque nut is required. The 7/8-14 fine thread pitch provides greater thread engagement and improved resistance to loosening compared to coarse-thread equivalents, making it well matched to applications subject to vibration or cyclical stress. The yellow zinc dichromate finish provides a baseline level of corrosion resistance in typical shop and field environments.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• Nylon insert locking mechanism provides prevailing torque without adhesives or secondary locking hardware
• 7/8-14 UNF fine thread for improved clamp load and vibration resistance
• Yellow zinc dichromate finish for corrosion protection and visual identification
• Right-hand thread direction compatible with standard fastener assemblies
• Inch-series dimensions conforming to UNF fastener standards

Compatibility

Designed as a standard UNF hex lock nut for use with any 7/8-14 right-hand threaded bolt or stud in Grade 8 or lower strength applications where prevailing-torque locking is required.

Installation Notes

Installation is performed by mechanics or maintenance technicians using a standard wrench sized for 1-1/4 inches across the flats. Power down or de-energize any associated equipment before disassembling fastened joints. Nylon insert lock nuts are generally intended for single use, as the locking insert may be degraded after removal. Do not use in applications where sustained temperatures exceed the service limit of the nylon insert material.
