Value Collection 367-0321 Hex Rethreading Die 1/2-13 Hss Unc

Product Description

The VALUE COLLECTION 367-0321 is a hex rethreading die designed to restore damaged or corroded external threads without requiring a lathe or threading machine. Sized for 1/2-13 Unified National Coarse thread form, this die cuts right-hand threads and is manufactured from high-speed steel for durability across repeated use. It weighs 0.25 pounds and is suited for maintenance, repair, and overhaul work where a fastener thread must be cleaned up and brought back to spec before reassembly. Machinists, millwrights, and general-trade technicians keep rethreading dies on hand for field and shop repairs alike.

This die is applicable wherever 1/2-13 UNC external threads appear on bolts, studs, or threaded rod. Common use cases include restoring threads on HVAC equipment structural fasteners, pipe-flange hardware, pump mounting studs, and mechanical assembly components. The right-hand thread direction matches the vast majority of standard fastener installations in residential and commercial mechanical systems. The hex profile accepts a standard die stock or adjustable wrench for manual threading.

Key Features

• 1/2-13 UNC thread size for one of the most common fastener specifications in mechanical and structural applications

Compatibility

Designed for use on any 1/2-13 UNC right-hand externally threaded fastener or stud where thread restoration is required. No specific model or OEM compatibility was provided in the product data.

Installation Notes

Rethreading dies are used by machinists, maintenance technicians, and trade professionals working on threaded fasteners in mechanical assemblies. Before use, clean the damaged thread area of debris, rust, and loose material. Apply cutting oil to the die and the work piece to reduce friction and improve thread quality. Always de-energize and lock out equipment before accessing any fastener that is part of a live mechanical or electrical assembly.
