Value Collection 367-1322 Hex Rethreading Die 1-1/2-12 Unf

Product Description

The VALUE COLLECTION 367-1322 is a hex rethreading die designed to restore damaged or corroded external threads to original specification. Built from high-speed steel, this die delivers the hardness and wear resistance required for repeated use on fasteners and threaded rod. It cuts a 1-1/2-12 UNF (Unified National Fine) right-hand thread profile and measures 1 inch thick. Machinists, maintenance technicians, and trade professionals reach for rethreading dies when a bolt, stud, or fitting has thread damage that makes assembly impossible without restoration. The hex outer profile seats securely in a standard die stock for controlled, repeatable passes.

This die is suited for thread restoration work on 1-1/2-inch diameter fasteners and threaded components calling for a 12 threads-per-inch fine-pitch UNF profile. Typical applications include repair of hydraulic fitting threads, heavy equipment studs, and industrial pipe and machinery fasteners where fine-thread engagement is specified. Right-hand thread direction matches the standard fastener convention used across virtually all North American mechanical assemblies.

Key Features

• 1-1/2-12 UNF thread size for fine-pitch restoration on 1-1/2-inch diameter stock
• High-speed steel construction for hardness and extended service life
• Right-hand thread direction matching standard fastener convention
• 1 inch thickness provides stable, full-depth thread cutting engagement
• Hex outer profile seats in a standard die stock for controlled torque application

Compatibility

Designed for use with standard hex die stocks sized to accept a hex rethreading die for 1-1/2-12 UNF right-hand thread profiles.

Installation Notes

Rethreading dies are typically used by machinists and maintenance trades. Before use, clean and de-burr the damaged threads with a wire brush and inspect the base material for cracks or deformation that would prevent a proper repair. Apply cutting oil to the die and the workpiece before each pass to reduce heat and extend die life. Advance the die in short increments, backing off periodically to clear chips and prevent binding.
