Value Collection 83919552 Hex Rethreading Die 1-3/8-12 Unf

Product Description

The VALUE COLLECTION 83919552 is a hex rethreading die designed to restore damaged or corroded external threads on fasteners, bolts, and fittings. Manufactured from high-speed steel (HSS), it delivers the hardness needed to clean and recut 1-3/8-12 UNF right-hand threads without deforming. At 1 inch thick, the die provides a stable cutting surface for consistent thread engagement. Maintenance technicians, machinists, and industrial service pros use rethreading dies to salvage threaded components rather than replace them, reducing downtime on equipment repairs.

This die is suited for shop and field use wherever 1-3/8-12 UNF right-hand external threads require restoration. Common applications include heavy equipment fasteners, hydraulic fittings, shafts, and structural hardware. The hex outer profile accepts a standard die stock or wrench for controlled torque during operation. It is appropriate for both production machine shops and maintenance-repair-operations (MRO) environments handling unified fine thread work.

Key Features

• High-speed steel construction for durability across repeated rethreading operations
• 1-3/8-12 UNF right-hand thread specification for unified fine thread restoration
• 1 inch thickness provides a full, stable cutting depth
• Hex outer profile compatible with standard die stocks and adjustable wrenches
• Right-hand thread direction matches the most common fastener standard

Compatibility

Designed as an OEM-style rethreading tool for restoring 1-3/8-12 UNF right-hand external threads on bolts, shafts, and fittings in industrial and mechanical service applications.

Installation Notes

Rethreading dies are typically used by machinists or maintenance technicians working on mechanical assemblies. Before use, secure the workpiece and ensure the die is properly seated in a die stock to maintain alignment with the thread axis. Apply appropriate cutting fluid to the die and workpiece to reduce heat and prolong cutting edge life. Inspect the restored threads with a mating nut or thread gauge before returning the component to service.
