Value Collection 446014BR Hex Lock Nut 5/8-11 Grade L9

Product Description

The VALUE COLLECTION 446014BR is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loading. Manufactured from Grade L9 steel with a cadmium dichromate finish, it delivers high tensile strength along with corrosion resistance suited to industrial and mechanical assembly environments. The nut follows a 5/8-11 UNC thread specification with right-hand thread direction, a width across flats of 0.9370 inches, and a height of 0.6600 inches. Electricians, millwrights, maintenance technicians, and mechanical assemblers working with heavy-duty fastener applications will find this nut appropriate for structural and equipment fastening tasks.

This hex lock nut is used in industrial machinery, equipment frames, structural assemblies, and mechanical systems where standard nuts may back off under vibration or cyclic loads. The distorted-thread locking style provides prevailing torque without the need for additional locking components such as washers or adhesives. It is well suited for use in manufacturing, maintenance, and repair operations where a reliable, reusable locking fastener is required in inch-series UNC applications.

Key Features

• Distorted-thread locking style provides prevailing torque resistance without secondary hardware
• Grade L9 steel construction for high tensile strength in demanding fastening applications
• Cadmium dichromate finish for corrosion protection in industrial environments
• 5/8-11 UNC right-hand thread for compatibility with standard inch-series fastener systems
• Width across flats of 0.9370 inches fits standard 15/16-inch hex tooling
• Height of 0.6600 inches suits typical heavy-duty hex nut installation envelopes

Compatibility

Designed for use with 5/8-11 UNC inch-series threaded fasteners and bolts in standard industrial and mechanical assembly applications.

Installation Notes

Installation should be performed by qualified mechanical assemblers or maintenance technicians familiar with fastener torque specifications for Grade L9 hardware. Power down and de-energize any equipment before servicing fastened assemblies. Use a standard open-end or box wrench sized for 0.9370-inch (15/16-inch nominal) across flats. Distorted-thread nuts may be reused a limited number of times before prevailing torque performance degrades; inspect locking effectiveness after each removal.
