Cle-line C65607 Hex Rethreading Die 3/8-24 Unf

Product Description

The CLE-LINE C65607 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Built from carbon steel, this die handles 3/8-24 UNF right-hand threads in a fixed, non-adjustable format. The hex body style allows a standard wrench or die stock to drive the tool with consistent torque. Rethreading dies are a go-to solution for field repair work where replacing a fastener or threaded component is not practical. Licensed tradespeople in HVAC, plumbing, and mechanical service use these tools to recondition bolt threads, fitting threads, and valve stems without removing the assembly from service.

This die is suited for use on 3/8-24 UNF threaded fasteners and fittings found in residential and light commercial mechanical systems. Typical applications include restoring threads on bolts, studs, and pipe fittings where corrosion, impact damage, or cross-threading has compromised the thread form. The right-hand thread direction matches the standard orientation for the vast majority of threaded components encountered in trade service work.

Key Features

• 3/8-24 UNF thread size for fine-thread fastener and fitting repair
• Right-hand thread direction matches standard fastener orientation
• Carbon steel construction provides adequate hardness for rethreading mild steel and softer base metals
• Hex body style accepts standard wrenches and die stocks for controlled driving
• Fixed, non-adjustable design delivers consistent thread form on every pass
• Series 0650 die - part of a matched rethreading set family for multi-size job coverage

Compatibility

Designed as an OEM-style replacement rethreading die for 3/8-24 UNF right-hand threaded fasteners and components in residential and commercial mechanical applications.

Installation Notes

Rethreading dies are typically used by HVAC technicians, plumbers, and mechanical contractors during maintenance or repair. Before rethreading, de-energize or shut off any system pressure to the component being serviced. Apply cutting oil to the die and the damaged thread before beginning to reduce heat and improve thread form quality. Drive the die slowly with steady, even torque using a properly sized wrench or die stock - do not force the tool past resistance.
