Value Collection 366-1332 Hex Rethreading Die 1-3/4-5 Unc

Product Description

The VALUE COLLECTION 366-1332 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Built from carbon steel, it delivers the hardness and edge retention needed to clean up distorted thread profiles without requiring removal of the fastener or fitting from the assembly. The die is configured for 1-3/4-5 UNC threads and measures 1 inch thick, providing the material engagement necessary for accurate thread restoration on larger-diameter fasteners and threaded rods.

This die is suited for maintenance, repair, and overhaul work across industrial, mechanical, and trade applications where large-diameter left-hand threaded fasteners require reconditioning. Left-hand thread configuration makes it specific to applications where reverse-thread fasteners are used, such as certain rotating equipment, specialty valves, and left-hand threaded fittings. It is typically used by machinists, millwrights, and maintenance technicians working on heavy equipment or industrial piping systems.

Key Features

• 1-3/4-5 UNC thread size for large-diameter thread restoration
• Left-hand thread direction for reverse-thread fastener applications
• Carbon steel construction for hardness and durability during thread chasing
• 1 inch thickness provides solid material engagement for accurate rethreading
• Hex body style for use with standard die stocks and wrenches

Compatibility

Designed as a rethreading die for 1-3/4-5 UNC left-hand external threads on fasteners, threaded rods, and fittings requiring thread restoration.

Installation Notes

This die is installed and operated by machinists or qualified maintenance technicians using an appropriate die stock or wrench sized for the hex body. Ensure the workpiece thread and die thread direction match before applying torque. Apply cutting oil to the die and workpiece before use to reduce friction and extend tool life. Inspect the die for wear or chipping before each use to avoid further damage to the workpiece threads.
