Value Collection 365-0282 Hex Rethreading Die 7/16-20 Unf

Product Description

The VALUE COLLECTION 365-0282 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. It cuts a 7/16-20 thread profile in the right-hand direction per the UNF (Unified National Fine) standard. Constructed from carbon steel, this die provides the hardness needed to chase and clean threads on common fastener materials encountered in HVAC, plumbing, and general mechanical work. The hex body form allows engagement with a standard open-end or box wrench, making it practical for field service and bench work alike.

This rethreading die is suited for maintenance and repair applications where a 7/16-20 UNF external thread has been damaged by corrosion, impact, or cross-threading. Typical use cases include restoring threads on bolts, studs, and fittings in residential and light commercial mechanical systems. It is not intended for cutting new threads in virgin material; it is a cleanup and restoration tool.

Key Features

• 7/16-20 UNF thread profile for right-hand external thread restoration
• Carbon steel construction provides adequate hardness for chasing threads on common fastener stock
• Hex body design accepts standard wrenches — no special die stock required for many applications
• Right-hand thread direction matches the vast majority of standard fastener applications
• Compact size suits both field service kits and bench toolboxes

Compatibility

Designed for use on 7/16-20 UNF right-hand external threads on bolts, studs, and threaded fittings in general mechanical, HVAC, plumbing, and electrical trade applications.

Installation Notes

This die is a thread restoration tool intended for use by qualified tradespeople. Before chasing threads on an installed fastener or fitting, de-energize or shut off the relevant system and relieve any pressure in the line. Apply a suitable cutting or tapping fluid to the die and the workpiece to reduce friction and improve thread finish. Work slowly and back off periodically to clear debris. Do not use this die to cut new threads in unthreaded material.
