Value Collection 446056PR Hex Lock Nut 3/8-24 Grade L9

Product Description

The VALUE COLLECTION 446056PR 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, this nut provides corrosion resistance and meets the demands of high-stress fastener applications. The 3/8-24 UNF thread size and right-hand thread direction make it a standard fit for fine-thread assemblies. At 0.562 inches across the flats and 0.400 inches in height, it suits compact fastener joints where secure retention is critical. Installed by mechanics, millwrights, and maintenance technicians across industrial and equipment service applications.

The 446056PR is suited for use in equipment assemblies, mechanical systems, and structural joints where fine-thread locking fasteners are required. The distorted-thread locking style works by deforming the nut thread slightly so it grips the bolt thread under load without the need for adhesives or secondary locking elements. This makes it appropriate for assemblies that require periodic disassembly while still demanding reliable retention during service.

Key Features

• Distorted-thread locking style resists loosening from vibration without adhesives
• Grade L9 steel construction for high-strength fastener applications
• Cadmium dichromate finish provides corrosion resistance
• 3/8-24 UNF right-hand thread for compatibility with fine-thread bolt patterns
• 0.562 inches across flats, 0.400 inches height for compact joint fitment

Compatibility

Designed as a standard distorted-thread hex lock nut for use with 3/8-24 UNF fine-thread fastener assemblies in industrial and mechanical maintenance applications.

Installation Notes

Install using a standard hex wrench or socket sized for 0.562-inch across-flats engagement. Torque to the value specified by the equipment manufacturer or applicable fastener standard for 3/8-24 UNF Grade L9 hardware. Inspect mating bolt threads for damage or contamination before assembly, as distorted-thread lock nuts depend on thread interference for locking performance. Do not reuse lock nuts in safety-critical joints if the locking action has been visibly reduced by prior installation cycles.
