Cle-line C65621 Hex Rethreading Die 7/8-14 Unf

Product Description

The CLE-LINE C65621 is a hex rethreading die designed to restore damaged or corroded external threads on bolts, studs, and fittings. It cuts a 7/8-14 UNF (Unified National Fine) right-hand thread profile and is manufactured from carbon steel for reliable performance in field and shop use. The hex body allows standard wrench or die-stock engagement, making it practical for tight-access rethreading jobs. This die is a non-adjustable, fixed-tolerance tool suited for cleanup and restoration work rather than cutting new threads from blank stock. Plumbers, pipefitters, and general maintenance mechanics keep rethreading dies like this one in their kits for bolt and fitting recovery on the job.

This die is intended for rethreading 7/8-14 UNF right-hand external threads on fasteners and threaded components found in mechanical assemblies, hydraulic fittings, and general industrial applications. It is appropriate for both shop bench use and field repair scenarios where a damaged thread needs to be chased back to spec without replacing the entire fastener or fitting.

Key Features

• 7/8-14 UNF thread size for fine-pitch external thread restoration
• Right-hand thread direction, the standard orientation for most fastener applications
• Carbon steel construction provides adequate hardness for thread chasing and cleanup
• Hex body design accepts a standard open-end wrench or adjustable wrench for easy torque application
• Non-adjustable fixed die - consistent thread profile on every pass
• Series 0650 - part of a matched rethreading die family for organized kit building

Compatibility

Designed for rethreading 7/8-14 UNF right-hand external threads on bolts, studs, and threaded fittings in mechanical and industrial maintenance applications.

Installation Notes

Rethreading dies are used by mechanics, pipefitters, and maintenance technicians. Before chasing a thread, clean the fastener or stud of debris, rust, and old thread compound. Apply a cutting oil or thread lubricant to the die and workpiece to reduce friction and improve thread quality. Never force the die past resistance - back it off periodically to clear chips and prevent die damage.
