Value Collection 366-0645 Hex Rethreading Die 1-1/8-8

Product Description

The VALUE COLLECTION 366-0645 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners, pipe fittings, and threaded rod. Built from carbon steel, it delivers the hardness needed to chase and reform thread profiles without deforming the die itself. This die cuts a 1-1/8-8 UNS thread form in a left-hand direction, making it the correct tool when standard right-hand dies cannot be used. At 1 inch thick and with a 2-inch hex body, it seats securely in a standard die stock or wrench. Machinists, pipefitters, and maintenance technicians typically reach for this tool during repair work on threaded components.

This rethreading die is suited for maintenance and repair applications across industrial, mechanical, and trade environments. It is used to clean up left-hand external threads on bolts, studs, and fittings where the original thread form has been damaged by corrosion, impact, or cross-threading. The left-hand thread direction is common in applications where counter-rotation would otherwise loosen a right-hand fastener, such as certain rotating shaft assemblies, specialty valve connections, and equipment with reverse-drive components.

Key Features

• 1-1/8-8 UNS thread size for a coarse unified thread form
• Left-hand thread direction for reverse-thread repair applications
• Carbon steel construction provides hardness for thread chasing and restoration
• 2-inch hex body fits standard die stocks and hex wrenches
• 1-inch thickness provides stability and engagement depth during use
• Sold as a single die, ready for immediate use

Compatibility

Designed as an OEM-style rethreading die for use with standard 2-inch hex die stocks compatible with 1-1/8-8 UNS left-hand external thread repair applications.

Installation Notes

This die is installed and operated by machinists, pipefitters, or experienced maintenance technicians. Secure the die firmly in an appropriately sized die stock before use, and ensure the workpiece is clamped or fixtured to prevent movement. Apply cutting oil to the die and workpiece threads to reduce friction and extend die life. Always confirm the thread direction before starting to avoid cross-threading or further thread damage.
