Cle-line C65606 Hex Rethreading Die 3/8-16 Unc

Product Description

The CLE-LINE C65606 is a hex rethreading die designed to restore damaged or corroded external threads without cutting new ones. Made from carbon steel, this fixed die accepts a standard hex wrench or die stock and works on 3/8-16 UNC right-hand threads. Rethreading dies are used by plumbers, electricians, HVAC technicians, and general trade mechanics to salvage threaded rod, bolts, pipe nipples, and fasteners that have been damaged by rust, impact, or cross-threading. The non-adjustable design ensures consistent thread geometry on every pass.

This die is suited for field repair and shop use wherever 3/8-16 UNC external threads need to be chased or restored. Common applications include rethreading HVAC equipment fasteners, pipe fittings, conduit fittings, and general mechanical assemblies. Its compact hex body fits standard die holders, making it easy to include in a service vehicle tool kit. The fixed design is ideal for straightforward restoration work where adjustability is not required.

Installation Notes

This die is intended for use by qualified trade professionals familiar with thread restoration procedures. Before rethreading any fastener or fitting, relieve system pressure, de-energize electrical circuits, and ensure the workpiece is secure. Apply cutting oil or thread lubricant to the die and workpiece before use to reduce heat buildup and improve thread quality. Follow applicable trade codes and safety practices when working on pressurized or energized systems.
