Cle-line C65615 Hex Rethreading Die 5/8-18 Unf

Product Description

The CLE-LINE C65615 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. It cuts a 5/8-18 right-hand thread profile to the UNF standard, making it a practical hand-tool solution for field repair and shop maintenance work. The die body is machined from carbon steel for hardness and durability under repeated use. This is a fixed, non-adjustable die suited for quick thread restoration without the setup time of adjustable alternatives. Machinists, mechanics, and maintenance technicians typically reach for this type of die when bolt or stud threads are too damaged for a nut to seat cleanly.

This rethreading die is used in general mechanical maintenance across industrial, automotive, and trade applications wherever 5/8-18 UNF right-hand threaded fasteners are present. Common scenarios include restoring lightly damaged bolt threads on equipment during repair cycles or cleaning up threads on stud ends before reassembly. The hex body profile allows standard wrench engagement for controlled hand-drive operation without a dedicated die stock.

Key Features

• 5/8-18 UNF right-hand thread specification for precise thread restoration
• Carbon steel construction provides hardness suitable for rethreading steel and softer fasteners
• Hex body profile accepts standard open-end or box wrenches - no die stock required
• Fixed, non-adjustable design for consistent thread form on every pass
• Compact and lightweight at 0.143 pounds for easy inclusion in a field tool kit

Compatibility

Designed for use on external fasteners with a 5/8-18 UNF right-hand thread form. Suitable for rethreading bolts, studs, and threaded rod ends in any application requiring this thread specification.

Installation Notes

Thread restoration work should be performed with the workpiece secured and all system energy isolated before service begins. Apply cutting oil or thread-cutting lubricant to the die before use to reduce friction and improve thread quality. Drive the die slowly with steady, even pressure, backing off periodically to clear chips. Inspect restored threads with a matching nut after the operation to confirm proper fit before reassembly.
