Cle-line C65609 Hex Rethreading Die 7/16-20 Unf

Product Description

The CLE-LINE C65609 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Built from carbon steel, this die handles 7/16-20 UNF right-hand threads and is used to clean up bolt threads, pipe fittings, and fastener shanks that have been cross-threaded, rusted, or otherwise compromised. It is a fixed, non-adjustable die suited for field repair and shop work alike. Machinists, mechanics, plumbers, and maintenance technicians reach for this type of die when a damaged fastener needs to be salvaged rather than replaced.

This rethreading die is used in both residential and commercial maintenance applications where threaded fasteners require reconditioning. Typical scenarios include restoring threads on bolts, studs, and fittings before reassembly. The hex body allows a standard wrench or die holder to drive the tool by hand with consistent control. It is part of the CLE-LINE Series 0650 rethreading die lineup.

Key Features

• Carbon steel construction provides durability for repeated use
• Fixed, non-adjustable design ensures consistent thread profile on every pass
• Hex body accepts standard wrenches or die stocks for controlled driving

Compatibility

Designed for use on 7/16-20 UNF right-hand threaded fasteners, bolts, and fittings requiring thread restoration or cleanup.

Installation Notes

Thread rethreading dies are used by machinists, mechanics, and trade professionals performing fastener repair. Always clean the workpiece of debris and apply appropriate cutting oil before running the die over damaged threads to reduce friction and improve thread quality. Secure the workpiece firmly before use and advance the die in short, controlled turns to avoid further thread damage. Inspect restored threads with a matching nut or thread gauge after use to confirm serviceability.
