Value Collection 446068BR Hex Lock Nut 7/8-14 Grade L9

Product Description

The VALUE COLLECTION 446068BR is a 7/8-14 UNF hex lock nut manufactured from Grade L9 steel with a cadmium dichromate finish. It uses a distorted thread locking style, which deforms a portion of the nut threads to create prevailing torque resistance without the need for chemical adhesives or separate locking inserts. The nut measures 1.312 inches across the flats and 0.887 inches in height. This fastener is suited for high-strength bolted assemblies where vibration resistance is required and re-usability of the locking function may be limited to a defined number of installation cycles.

This hex lock nut is used in industrial, automotive, agricultural, and heavy equipment applications where a 7/8-14 fine-thread fastener is specified and vibration or dynamic loading is a concern. It is installed by mechanics, machinists, and maintenance technicians working on assemblies that demand reliable thread retention under load. The right-hand thread direction is standard for the majority of bolted joint applications.

Key Features

• Distorted thread locking style provides prevailing torque without adhesives or secondary locking elements
• Grade L9 steel construction for high tensile strength applications
• Cadmium dichromate finish provides corrosion and oxidation resistance
• 7/8-14 UNF right-hand thread for compatibility with fine-thread bolt patterns
• 1.312-inch width across flats for standard hex wrench or socket engagement
• 0.887-inch height profile suitable for standard hex lock nut clearance envelopes

Compatibility

Designed for use with 7/8-14 UNF right-hand threaded fasteners in inch-measurement bolted assemblies where a prevailing torque hex lock nut is specified.

Installation Notes

Installation should be performed with a properly sized hex socket or open-end wrench matching the 1.312-inch across-flats dimension. Distorted thread lock nuts generate prevailing torque on engagement and may show increased wear on the locking section with each removal and reinstallation cycle; inspect before reuse in critical joints. Always ensure the mating bolt thread class and grade are compatible with a Grade L9 nut before assembly. Follow applicable industry or equipment manufacturer torque specifications for the joint being assembled.
