Value Collection 365-0321 Hex Rethreading Die 1/2-13 Unc

Product Description

The VALUE COLLECTION 365-0321 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Made from carbon steel, this die cuts a 1/2-13 UNC thread in the right-hand direction, making it suitable for restoring standard fastener threads on bolts, studs, and rods. It is a practical tool for maintenance, repair, and overhaul work across mechanical, plumbing, and HVAC service applications. The hex body allows use with a standard wrench or adjustable wrench, speeding up thread restoration on the job or in the shop.

This rethreading die is suited for use in residential and light commercial maintenance scenarios where fasteners with damaged threads need to be restored rather than replaced. It is commonly used by HVAC technicians, plumbers, pipefitters, and general maintenance professionals working on threaded connections that have sustained corrosion, cross-threading, or mechanical damage. Its compact size makes it easy to carry in a service bag or toolbox for field use.

Installation Notes

This die is used by maintenance and trade professionals to chase and restore damaged external threads. Before use, de-energize and isolate any equipment the fastener is associated with. Apply cutting oil to the die and fastener threads to reduce friction and extend die life. Run the die slowly and back off periodically to clear debris from the cutting flutes.
