Value Collection 365-1246 Hex Rethreading Die 1-3/8-18

Product Description

The VALUE COLLECTION 365-1246 is a hex rethreading die designed to restore damaged or corroded external threads to their original specification. Built from carbon steel, this die cuts right-hand threads in the 1-3/8-18 UNEF (Unified Extra Fine) thread standard. At 1 inch thick, it provides the rigidity needed for accurate thread restoration on bolts, studs, and threaded rod. Plumbers, pipefitters, HVAC techs, and maintenance mechanics reach for rethreading dies when field-damaged fasteners need to be salvaged rather than replaced. This die fits standard hex die stocks and handles compatible with its 1-3/8-inch outside diameter.

This die is suited for use in maintenance, repair, and overhaul work across residential, commercial, and light industrial settings. Typical applications include restoring threads on equipment mounting studs, valve stems, and structural fasteners where the 1-3/8-18 UNEF thread form is specified. Right-hand thread direction matches the vast majority of standard fastener applications. The carbon steel construction holds a cutting edge through repeated use on mild steel and similar materials.

Key Features

• 1-3/8-18 UNEF thread specification for extra fine pitch thread restoration
• Right-hand thread direction — matches standard fastener orientation
• Carbon steel construction for durability and cutting edge retention
• 1 inch thickness provides stability during threading operations
• Hex body design fits standard die stocks and handle sets

Compatibility

Designed for use with standard hex die stocks and handles that accept a die sized for the 1-3/8-18 UNEF thread form. Compatible with mild steel fasteners and threaded components requiring right-hand thread restoration.

Installation Notes

This die is installed and operated by machinists, maintenance mechanics, and trade professionals familiar with threading tools. Secure the workpiece firmly before engaging the die to prevent movement during thread cutting. Apply cutting oil generously to the threads and die throughout the operation to reduce friction and extend die life. Follow all applicable shop safety practices, including eye protection, when performing threading operations.
